Moving Truenas Apps data from 1 volume to another volume

I have 2 apps configured in Apps in Truenas (immich as well as Openspeedtest.)
I would like to move all the data from 1 volume to another

Ive tried chosing another Pool and that seem to be OK by all my Apps are empty when i choose the other Pool.

IS there a way to do this eithe automaticly or via Manual.
