View MariaDB export and import instructions
-
-If the app uses a MariaDB database, we need to make a backup and restore that backup to the new app's database.
-
-:::note[Requirements]
-
-Make sure you have `adminer` installed, as we'll be using it to make a backup and to restore the database. It's a TrueCharts app from the stable train. You can install it with all default settings, and it will work.

-
-### Configure database connections in adminer
-
-To get the MariaDB credentials from each install the easiest way (until a script does this) is logging into the main container shell and typing `env`, which pulls down the list of `environment variables` used by the container, including the `database credentials`.
-
-
-
-Repeat the same for the "new" app
-
-
-
-### Create database Backup
-
-Login to `adminer` using the 4 values highlighted in red above. For most users it'll be `appname-mariadb.ix-appname.svc.cluster.local:3306` or in this case `photoprism-mariadb.ix-photoprism.svc.cluster.local:3306`
-
-
-
-Click `Export`, choose a compression output (gzip) and press `export`
-
-
-
-### Restore database backup
-
-Now you login to `adminer` with the "new" app
-
-
-
-Click `Import`, then `Choose Files`, upload your backup and then click `Execute`
