What does it mean to "choose a pool" in App configuration

Apps and Virtualization
1

I am running TrueNAS scale ElectricEel-24.10.2. I am consolidating my pools int one now that there is the ability to add new drives to a pool. Part of this is to move the apps from one of my old pools to another pool I am expanding. I have four apps installed, one of which is “filebrowser” that I am testing the migration process with. My process is to stop my app, select my new pool and then add a new app in the new pool before going back and deleting the same app from my old pool. Everything works great. But I see no changes at all in my new pool. I would have expected at least some files to contain the app config but I see nothing. Am I doing somethig wrong?

Thanks

Choosing a pool defines where the hidden ix-applications dataset will be placed. By default that stores all apps and their data. If you use host paths for app volumes instead, that overrides that default.
