+Your migration **must be** reversible. This is very important, as it should
 be possible to downgrade in case of a vulnerability or bugs.
 
 In your migration, add a comment describing how the reversibility of the

+## Multi Threading
+
+Sometimes a migration might need to use multiple Ruby threads to speed up a
+migration. For this to work your migration needs to include the module
+`Gitlab::Database::MultiThreadedMigration`:
+
+```ruby
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+  include Gitlab::Database::MultiThreadedMigration
+end
+```
+
+You can then use the method `with_multiple_threads` to perform work in separate
+threads. For example:
+
+```ruby
+class MyMigration < ActiveRecord::Migration
+  include Gitlab::Database::MigrationHelpers
+  include Gitlab::Database::MultiThreadedMigration
+
+  def up
+    with_multiple_threads(4) do
+      disable_statement_timeout
+
+      # ...
+    end
+  end
+end
+```
+
+Here the call to `disable_statement_timeout` will use the connection local to
+the `with_multiple_threads` block, instead of re-using the global connection
+pool.  This ensures each thread has its own connection object, and won't time
+out when trying to obtain one.
+
+**NOTE:** PostgreSQL has a maximum amount of connections that it allows. This
+limit can vary from installation to installation. As a result it's recommended
+you do not use more than 32 threads in a single migration. Usually 4-8 threads
+should be more than enough.

+## Upgrading without downtime
+
+Starting with GitLab 9.1.0 it's possible to upgrade to a newer version of GitLab
+without having to take your GitLab instance offline. However, for this to work
+there are the following requirements:
+
+1. You can only upgrade 1 release at a time. For example, if 9.1.15 is the last
+   release of 9.1 then you can safely upgrade from that version to 9.2.0.
+   However, if you are running 9.1.14 you first need to upgrade to 9.1.15.
+2. You have to use [post-deployment
+   migrations](../development/post_deployment_migrations.md).
+3. You are using PostgreSQL. If you are using MySQL you will still need downtime
+   when upgrading.
+
+This applies to major, minor, and patch releases unless stated otherwise in a
+release post.
