Hi, I need some help and I’m in over my head on this one…I migrated form Core to Core to scale (Dragonfish) and got my apps set up and working, but when I migrated to Electric Eel 2 of the 3 apps migrated but my Plerx setup didn’t…I don’t know what to do to resolve this…all help welcome.

This has been resolved. I wish i could give eyo concise response on how…I
refreshed the catalog in EE, I ran through steps that were suggested from the reddit version of this post, I tried the migration multiple times and eventually saw a log message about the Plex template failed because it got ‘namespace’ and was expecting ‘dns opt’. I rolled back to dragonfish and edited the plex app config removing namespace entries (there were 2 representing my networks and DNS), then remigrated and plex migrated successfully.
