+# From 10.0 to 10.1
+
+Make sure you view this update guide from the tag (version) of GitLab you would
+like to install. In most cases this should be the highest numbered production
+tag (without rc in it). You can select the tag in the version dropdown at the
+top left corner of GitLab (below the menu bar).
+
+If the highest number stable branch is unclear please check the
+[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
+guide links by version.
+
+### 1. Stop server
+
+```bash
+sudo service gitlab stop
+```
+
+### 2. Backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+```
+
+### 3. Update Ruby
+
+NOTE: GitLab 9.0 and higher only support Ruby 2.3.x and dropped support for Ruby 2.1.x. Be
+sure to upgrade your interpreter if necessary.
+
+You can check which version you are running with `ruby -v`.
+
+Download and compile Ruby:
+
+```bash
+mkdir /tmp/ruby && cd /tmp/ruby
+curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.5.tar.gz
+echo '3247e217d6745c27ef23bdc77b6abdb4b57a118f  ruby-2.3.5.tar.gz' | shasum -c - && tar xzf ruby-2.3.5.tar.gz
+cd ruby-2.3.5
+./configure --disable-install-rdoc
+make
+sudo make install
+```
+
+Install Bundler:
+
+```bash
+sudo gem install bundler --no-ri --no-rdoc
+```
+
+### 4. Update Node
+
+GitLab now runs [webpack](http://webpack.js.org) to compile frontend assets and
+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running
+a version older than `v4.3.0` you will need to update to a newer version.  You
+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+
+
+Since 8.17, GitLab requires the use of yarn `>= v0.17.0` to manage
+JavaScript dependencies.
+
+```bash
+curl --silent --show-error https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
+echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
+sudo apt-get update
+sudo apt-get install yarn
+```
+
+More information can be found on the [yarn website](https://yarnpkg.com/en/docs/install).
+
+### 5. Update Go
+
+NOTE: GitLab 9.2 and higher only supports Go 1.8.3 and dropped support for Go
+1.5.x through 1.7.x. Be sure to upgrade your installation if necessary.
+
+You can check which version you are running with `go version`.
+
+Download and install Go:
+
+```bash
+# Remove former Go installation folder
+sudo rm -rf /usr/local/go
+
+curl --remote-name --progress https://storage.googleapis.com/golang/go1.8.3.linux-amd64.tar.gz
+echo '1862f4c3d3907e59b04a757cfda0ea7aa9ef39274af99a784f5be843c80c6772  go1.8.3.linux-amd64.tar.gz' | shasum -a256 -c - && \
+  sudo tar -C /usr/local -xzf go1.8.3.linux-amd64.tar.gz
+sudo ln -sf /usr/local/go/bin/{go,godoc,gofmt} /usr/local/bin/
+rm go1.8.3.linux-amd64.tar.gz
+```
+
+### 6. Get latest code
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git fetch --all
+sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
+sudo -u git -H git checkout -- locale
+```
+
+For GitLab Community Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-1-stable
+```
+
+OR
+
+For GitLab Enterprise Edition:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H git checkout 10-1-stable-ee
+```
+
+### 7. Update gitlab-shell
+
+```bash
+cd /home/git/gitlab-shell
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_SHELL_VERSION)
+sudo -u git -H bin/compile
+```
+
+### 8. Update gitlab-workhorse
+
+Install and compile gitlab-workhorse. GitLab-Workhorse uses
+[GNU Make](https://www.gnu.org/software/make/).
+If you are not using Linux you may have to run `gmake` instead of
+`make` below.
+
+```bash
+cd /home/git/gitlab-workhorse
+
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITLAB_WORKHORSE_VERSION)
+sudo -u git -H make
+```
+
+### 9. Update Gitaly
+
+#### New Gitaly configuration options required
+
+In order to function Gitaly needs some additional configuration information. Below we assume you installed Gitaly in `/home/git/gitaly` and GitLab Shell in `/home/git/gitlab-shell'.
+
+```shell
+echo '
+[gitaly-ruby]
+dir = "/home/git/gitaly/ruby"
+
+[gitlab-shell]
+dir = "/home/git/gitlab-shell"
+' | sudo -u git tee -a /home/git/gitaly/config.toml
+```
+
+#### Check Gitaly configuration
+
+Due to a bug in the `rake gitlab:gitaly:install` script your Gitaly
+configuration file may contain syntax errors. The block name
+`[[storages]]`, which may occur more than once in your `config.toml`
+file, should be `[[storage]]` instead.
+
+```shell
+sudo -u git -H sed -i.pre-10.1 's/\[\[storages\]\]/[[storage]]/' /home/git/gitaly/config.toml
+```
+
+#### Compile Gitaly
+
+```shell
+cd /home/git/gitaly
+sudo -u git -H git fetch --all --tags
+sudo -u git -H git checkout v$(</home/git/gitlab/GITALY_SERVER_VERSION)
+sudo -u git -H make
+```
+
+### 10. Update MySQL permissions
+
+If you are using MySQL you need to grant the GitLab user the necessary
+permissions on the database:
+
+```bash
+mysql -u root -p -e "GRANT TRIGGER ON \`gitlabhq_production\`.* TO 'git'@'localhost';"
+```
+
+If you use MySQL with replication, or just have MySQL configured with binary logging,
+you will need to also run the following on all of your MySQL servers:
+
+```bash
+mysql -u root -p -e "SET GLOBAL log_bin_trust_function_creators = 1;"
+```
+
+You can make this setting permanent by adding it to your `my.cnf`:
+
+```
+log_bin_trust_function_creators=1
+```
+
+### 11. Update configuration files
+
+#### New configuration options for `gitlab.yml`
+
+There might be configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-0-stable:config/gitlab.yml.example origin/10-1-stable:config/gitlab.yml.example
+```
+
+#### Nginx configuration
+
+Ensure you're still up-to-date with the latest NGINX configuration changes:
+
+```sh
+cd /home/git/gitlab
+
+# For HTTPS configurations
+git diff origin/10-0-stable:lib/support/nginx/gitlab-ssl origin/10-1-stable:lib/support/nginx/gitlab-ssl
+
+# For HTTP configurations
+git diff origin/10-0-stable:lib/support/nginx/gitlab origin/10-1-stable:lib/support/nginx/gitlab
+```
+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this
+via [/etc/default/gitlab].
+
+[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
+[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-1-stable/lib/support/init.d/gitlab.default.example#L38
+
+#### SMTP configuration
+
+If you're installing from source and use SMTP to deliver mail, you will need to add the following line
+to config/initializers/smtp_settings.rb:
+
+```ruby
+ActionMailer::Base.delivery_method = :smtp
+```
+
+See [smtp_settings.rb.sample] as an example.
+
+[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/10-1-stable/config/initializers/smtp_settings.rb.sample#L13
+
+#### Init script
+
+There might be new configuration options available for [`gitlab.default.example`][gl-example]. View them with the command below and apply them manually to your current `/etc/default/gitlab`:
+
+```sh
+cd /home/git/gitlab
+
+git diff origin/10-0-stable:lib/support/init.d/gitlab.default.example origin/10-1-stable:lib/support/init.d/gitlab.default.example
+```
+
+Ensure you're still up-to-date with the latest init script changes:
+
+```bash
+cd /home/git/gitlab
+
+sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
+```
+
+For Ubuntu 16.04.1 LTS:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+### 12. Install libs, migrations, etc.
+
+```bash
+cd /home/git/gitlab
+
+# MySQL installations (note: the line below states '--without postgres')
+sudo -u git -H bundle install --without postgres development test --deployment
+
+# PostgreSQL installations (note: the line below states '--without mysql')
+sudo -u git -H bundle install --without mysql development test --deployment
+
+# Optional: clean up old gems
+sudo -u git -H bundle clean
+
+# Run database migrations
+sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
+
+# Compile GetText PO files
+
+sudo -u git -H bundle exec rake gettext:compile RAILS_ENV=production
+
+# Update node dependencies and recompile assets
+sudo -u git -H bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production
+
+# Clean up cache
+sudo -u git -H bundle exec rake cache:clear RAILS_ENV=production
+```
+
+**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
+
+### 13. Start application
+
+```bash
+sudo service gitlab start
+sudo service nginx restart
+```
+
+### 14. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+```
+
+To make sure you didn't miss anything run a more thorough check:
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+```
+
+If all items are green, then congratulations, the upgrade is complete!
+
+## Things went south? Revert to previous version (9.5)
+
+### 1. Revert the code to the previous version
+
+Follow the [upgrade guide from 9.4 to 9.5](9.4-to-9.5.md), except for the
+database migration (the backup is already migrated to the previous version).
+
+### 2. Restore from the backup
+
+```bash
+cd /home/git/gitlab
+
+sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
+```
+
+If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.

-*** NOTE: These instructions should be considered deprecated. In GitLab 10.0 we will be releasing new migration instructions using [pgloader](http://pgloader.io/).

-# Migrating GitLab from MySQL to Postgres
-*Make sure you view this [guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/mysql_to_postgresql.md#migrating-gitlab-from-mysql-to-postgres) for the most up to date instructions.*
+# Migrating from MySQL to PostgreSQL
 
-If you are replacing MySQL with Postgres while keeping GitLab on the same server all you need to do is to export from MySQL, convert the resulting SQL file, and import it into Postgres. If you are also moving GitLab to another server, or if you are switching to omnibus-gitlab, you may want to use a GitLab backup file. The second part of this documents explains the procedure to do this.
+> **Note:** This guide assumes you have a working Omnibus GitLab instance with
+> MySQL and want to migrate to bundled PostgreSQL database.
 
-## Export from MySQL and import into Postgres
+## Prerequisites
 
-Use this if you are keeping GitLab on the same server.
+First, we'll need to enable the bundled PostgreSQL database with up-to-date
+schema. Next, we'll use [pgloader](http://pgloader.io) to migrate the data
+from the old MySQL database to the new PostgreSQL one.
 
-```
-sudo service gitlab stop
+Here's what you'll need to have installed:
 
-# Update /home/git/gitlab/config/database.yml
+- pgloader 3.4.1+
+- Omnibus GitLab
+- MySQL
 
-git clone https://github.com/gitlabhq/mysql-postgresql-converter.git -b gitlab
-cd mysql-postgresql-converter
-mysqldump --compatible=postgresql --default-character-set=utf8 -r gitlabhq_production.mysql -u root gitlabhq_production -p
-python db_converter.py gitlabhq_production.mysql gitlabhq_production.psql
-ed -s gitlabhq_production.psql < move_drop_indexes.ed
+## Enable bundled PostgreSQL database
 
-# Import the database dump as the application database user
-sudo -u git psql -f gitlabhq_production.psql -d gitlabhq_production
+1. Stop GitLab:
 
-# Install gems for PostgreSQL (note: the line below states '--without ... mysql')
-sudo -u git -H bundle install --without development test mysql --deployment
+    ``` bash
+    sudo gitlab-ctl stop
+    ```
 
-sudo service gitlab start
-```
+1. Edit `/etc/gitlab/gitlab.rb` to enable bundled PostgreSQL:
 
-## Converting a GitLab backup file from MySQL to Postgres
-**Note:** Please make sure to have Python 2.7.x (or higher) installed.
+    ```
+    postgresql['enable'] = true
+    ```
 
-GitLab backup files (`<timestamp>_gitlab_backup.tar`) contain a SQL dump. Using the lanyrd database converter we can replace a MySQL database dump inside the tar file with a Postgres database dump. This can be useful if you are moving to another server.
+1. Edit `/etc/gitlab/gitlab.rb` to use the bundled PostgreSQL. Please check
+   all the settings beginning with `db_`, such as `gitlab_rails['db_adapter']`
+   and alike. You could just comment all of them out so that we'll just use
+   the defaults.
 
-```
-# Stop GitLab
-sudo service gitlab stop
+1. [Reconfigure GitLab] for the changes to take effect:
+
+    ``` bash
+    sudo gitlab-ctl reconfigure
+    ```
+
+1. Start Unicorn and PostgreSQL so that we could prepare the schema:
+
+    ``` bash
+    sudo gitlab-ctl start unicorn
+    sudo gitlab-ctl start posgresql
+    ```
+
+1. Run the following commands to prepare the schema:
+
+    ``` bash
+    sudo gitlab-rake db:create db:migrate
+    ```
+
+1. Stop Unicorn in case it's interfering the next step:
 
-# Create the backup
-cd /home/git/gitlab
-sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
+    ``` bash
+    sudo gitlab-ctl stop unicorn
+    ```
 
-# Note the filename of the backup that was created. We will call it
-# TIMESTAMP_gitlab_backup.tar below.
+After these steps, you'll have a fresh PostgreSQL database with up-to-date schema.
 
-# Move the backup file we will convert to its own directory
-sudo -u git -H mkdir -p tmp/backups/postgresql
-sudo -u git -H mv tmp/backups/TIMESTAMP_gitlab_backup.tar tmp/backups/postgresql/
+## Migrate data from MySQL to PostgreSQL
 
-# Create a separate database dump with PostgreSQL compatibility
-cd tmp/backups/postgresql
-sudo -u git -H mysqldump --compatible=postgresql --default-character-set=utf8 -r gitlabhq_production.mysql -u root gitlabhq_production -p
+Now, you can use pgloader to migrate the data from MySQL to PostgreSQL:
 
-# Clone the database converter
-sudo -u git -H git clone https://github.com/gitlabhq/mysql-postgresql-converter.git -b gitlab
+1. Save the following snippet in a `commands.load` file, and edit with your
+   database `username`, `password` and `host`:
 
-# Convert gitlabhq_production.mysql
-sudo -u git -H mkdir db
-sudo -u git -H python mysql-postgresql-converter/db_converter.py gitlabhq_production.mysql db/database.sql
-sudo -u git -H ed -s db/database.sql < mysql-postgresql-converter/move_drop_indexes.ed
+    ```
+    LOAD DATABASE
+         FROM mysql://username:password@host/gitlabhq_production
+         INTO postgresql://gitlab-psql@unix://var/opt/gitlab/postgresql:/gitlabhq_production
 
-# Compress database backup
-# Warning: If you have Gitlab 7.12.0 or older skip this step and import the database.sql directly into the backup with:
-# sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql
-# The compressed databasedump is not supported at 7.12.0 and older.
-sudo -u git -H gzip db/database.sql
+    WITH include no drop, truncate, disable triggers, create no tables,
+         create no indexes, preserve index names, no foreign keys,
+         data only
 
-# Replace the MySQL dump in TIMESTAMP_gitlab_backup.tar.
+    ALTER SCHEMA 'gitlabhq_production' RENAME TO 'public'
 
-# Warning: if you forget to replace TIMESTAMP below, tar will create a new file
-# 'TIMESTAMP_gitlab_backup.tar' without giving an error.
+    ;
+    ```
 
-sudo -u git -H tar rf TIMESTAMP_gitlab_backup.tar db/database.sql.gz
+1. Start the migration:
 
-# Done! TIMESTAMP_gitlab_backup.tar can now be restored into a Postgres GitLab
-# installation.
-# See https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/raketasks/backup_restore.md for more information about backups.
+    ``` bash
+    sudo -u gitlab-psql pgloader commands.load
+    ```
+
+1. Once the migration finishes, start GitLab:
+
+    ``` bash
+    sudo gitlab-ctl start
+    ```
+
+Now, you can verify that everything worked by visiting GitLab.
+
+## Troubleshooting
+
+### Experiencing 500 errors after the migration
+
+If you experience 500 errors after the migration, try to clear the cache:
+
+``` bash
+sudo gitlab-rake cache:clear
 ```
