Problem migrating data

[jk]

Hi,

I just moved to a new machine. As usual, the restoration process went fairly smoothly.

There is one issue remaining though, impacting two apps.

Both were configured to use an external media mount (the kind that is included in backup), which was a secondary disk. That disk is unavailable on the new machine.

For these two apps, the restoration failed, because it this disk could not be found. I tried to set the apps storage to use the default storage, but I couldn't because they are in error state.

What do I need to do to fix this issue and get the apps up-and-running again with their data?
