Backup and Database Upgrade

When all the running batch workflows have stopped you should make a backup so that the system can be restored in case of any issues during the upgrade.

Note

Note!

Before proceeding with the backup you must shut down the platform. This is very important since otherwise the backup of the database may become corrupt.

The platform can be shut down in various ways, see examples below.

Info

Examples - Shutting Down the Platform

where uepe is the namespace used.

Option 2

Run this command:

Code Block
kubectl scale --replicas=0 sts/platform -n uepe
