For example, if you are using AWS Aurora and are preparing to enable Database Load Balancing, you will need to move your databases to RDS for PostgreSQL. To move databases from one instance to another: 1. Gather the source and destination PostgreSQL endpoint information: ```shell SRC_PGHOST= SRC_PGUSER= DST_PGHOST= DST_PGUSER= ``` 1. Stop GitLab: ```shell sudo gitlab-ctl stop ``` 1. Dump the databases from the source: ```shell /opt/gitlab/embedded/bin/pg_dump -h $SRC_PGHOST -U $SRC_PGUSER -c -C -f gitlabhq_production.sql gitlabhq_production /opt/gitlab/embedded/bin/pg_dump -h $SRC_PGHOST -U $SRC_PGUSER -c -C -f praefect_production.sql praefect_production ``` 1. Restore the databases to the destination (this will overwrite any existing databases with the same names): ```shell /opt/gitlab/embedded/bin/psql -h $DST_PGHOST -U $DST_PGUSER -f praefect_production.sql postgres /opt/gitlab/embedded/bin/psql -h $DST_PGHOST -U $DST_PGUSER -f gitlabhq_production.sql postgres ``` 1. Configure the GitLab application servers with the appropriate connection details for your destination PostgreSQL instance in your `/etc/gitlab/gitlab.rb` file: ```ruby gitlab_rails['db_host'] = '' ``` For more information on GitLab multi-node setups, refer to the [reference architectures](../reference_architectures/index.md). 1. Reconfigure for the changes to take effect: ```shell sudo gitlab-ctl reconfigure ``` 1. Restart GitLab: ```shell sudo gitlab-ctl start ```
