Migrate Nextcloud App to Different Pool?

Hi everyone,

When I first set up my new NAS with TrueNAS SCALE, only the HDDs had arrived but the SSDs hadn’t. They were delayed. As such, I set everything up to use the HDD storage, including apps.

Is it possible to migrate my apps from the HDD pool to the SSD pool without losing data? The other apps are fine if not, but Nextcloud is especially critical.
