Re: Migration from Rocky Linux 9 to Debian 13 - problem with Thunderbird

I've been using Thunderbird since the first release more than two
decades ago. I'm handling multiple mail accounts, address books, agenda
and tasks with OwnCloud synchronization, RSS feeds, etc.
Up until now, backing up and restoring Thunderbird was a no-brainer.
Just transfer the whole ~/.thunderbird directory and its contents to an
external hard disk, install or upgrade the system, and then restore
the .thunderbird directory to its correct location in ~. I've done this
hundreds of times for me and some others (I'm a sysadmin in our local
school running Linux since 2010).
Right now I have a weird and nasty surprise. I made a backup of my old
Rocky Linux 9 installation, installed Debian 13 Trixie, restored the
data, moved the .thunderbird directory (about 4 GB) to its correct
location in ~, but instead of my mail accounts and my configuration, I
just see Thunderbird's configuration assistant.
Any suggestions ? Did the good folks at Debian change something under
the hood for this release ?
I'll answer this myself, since I just found the solution.
Start Thunderbird on the command line using the -ProfileManager option
and then select the correct profile.
Cheers,
Niki
