Migrating apps using a hostpath storage config to a new app pool

Hi all, I am using my HDD pool as my main app pool, and want to migrate to my SSD pool for apps. My apps are already on storage host paths pointing to the SSD app pool, and had some questions before I made any major changes:

  1. Since the host paths are already pointed at the SSD pool, would migrating to the SSD Pool be a moot point?
  2. I’ve seen posts where ix-apps is migrated automatically, does this also apply to apps using host path?

If a manual migration is needed for the apps, I envision the manual migration to go something like this… am I off-base?

  1. Changing the current app pool to the SSD pool.
  2. Manually installing apps from “Discover Apps” (mine are all stable/community builds) and setting the storage configs to the previously defined datasets.

Thanks!

Pre 24.10 versions of TrueNAS supported moving apps from pool to pool, now they don’t.

So therefore you need to do exactly what you said, aka

  1. Changing current app pool to SSD
  2. Manually install apps again and setting the storage configs to previous datasets and redoing settings, etc

I’m in a similar situation. I have two datasets. One is for my apps, called SSD, and the other is for all my data. Previously the apps Dataset was only one SSD. I put in a second SSD but stupidly extended the dataset instead of creating a mirror. I am now wanting to create a mirrored datasets that I can migrate my apps to. Is it as simple as setting up a mirrored dataset and changing the assigned pool for apps under Apps > Configuration > Choose Pool? I am currently on 25.04.2.4.

@StevenMcE your help would be greatly appreciated!

Or wait for 25.10 when there’s a button when you Choose another pool to migrate apps
