## Converting a GitLab backup file from MySQL to Postgres
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.
```
# Stop GitLab
sudo service gitlab stop
# Create the backup
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
# Note the filename of the backup that was created. We will call it
# TIMESTAMP_gitlab_backup.tar below.
# 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/
# 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
# Clone the database converter
sudo -u git -H git clone https://github.com/lanyrd/mysql-postgresql-converter.git
# 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
# Replace the MySQL dump in TIMESTAMP_gitlab_backup.tar.
# 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
# Done! TIMESTAMP_gitlab_backup.tar can now be restored into a Postgres GitLab installation.
