App pool migrate to bigger drive

Hi everyone. Running on Scale 24.10 and due to the unreliability errors on the Apps pool I would like to migrate to a new drive. I have searched everywhere but still haven’t found the solution how to do it properly. There was one promising solution:

  1. Navigate to Apps
  2. Stop all applications
  3. Click the Settings dropdown (second option from the upper right) and select “Choose Pool”
  4. Select a new pool from the dropdown list, and hit “Choose”
  5. TrueNAS will prompt you to confirm if you would like to migrate the data. If you chose to, it will now replicate the dataset and update the app settings automatically.

but it doesn’t prompt me if I want to migrate the apps pool.

How can I do app pool migration?
