 # Migrating GitLab from MySQL to Postgres
 *Make sure you view this [guide from the `master` branch](../../../master/doc/update/mysql_to_postgresql.md) for the most up to date instructions.*
 
-If you are replacing MySQL with Postgres while keeping GitLab on the same server all you need to do is to export from MySQL, import into Postgres and rebuild the indexes as described below. 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.

-## Rebuild indexes
-
-The lanyrd database converter script does not preserve all indexes, so we have to recreate them ourselves after migrating from MySQL. It is not necessary to shut down GitLab for this process.
-
-### For non-omnibus installations
-
-On non-omnibus installations (distributed using Git) we retrieve the index declarations from version control using `git stash`.
-
-```
-# Clone the database converter on your Postgres-backed GitLab server
-cd /tmp
-git clone https://github.com/gitlabhq/mysql-postgresql-converter.git -b gitlab
-
-cd /home/git/gitlab
-
-# Stash changes to db/schema.rb to make sure we can find the right index statements
-sudo -u git -H git stash
-
-# Generate add_index.rb
-ruby /tmp/mysql-postgresql-converter/add_index_statements.rb db/schema.rb > /tmp/mysql-postgresql-converter/add_index.rb
-
-# Create the indexes
-sudo -u git -H bundle exec rails runner -e production 'eval $stdin.read' < /tmp/mysql-postgresql-converter/add_index.rb
-```
-
-### For omnibus-gitlab installations
-
-On omnibus-gitlab we need to get the index declarations from a file called `schema.rb.bundled`. For versions older than 6.9, we need to download the file.
