Switch Backup Target on Kolla-ansible
The first step is to remove the datamover container and to unmount the old mounts. This is necessary to make sure, that the new datamover container with the new backend target is not getting any interference from the old backup target.

Edit the globals.yml file to contain the new backup target.
Follow the installation documentation to learn about the globals.yml TrilioVault variables.
