# Moving GitLab databases to a different PostgreSQL instance **(FREE SELF)**
|
||
|
|
|
||
|
|
Sometimes it is necessary to move your databases from one PostgreSQL instance to
|
||
|
|
another. 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=<source postgresql host>
|
||
|
|
SRC_PGUSER=<source postgresql user>
|
||
|
|
|
||
|
|
DST_PGHOST=<destination postgresql host>
|
||
|
|
DST_PGUSER=<destination postgresql user>
|
||
|
|
```
|
||
|
|
|
||
|
|
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'] = '<destination postgresql 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
|
||
|
|
```
