Back in the days when I was studying Computer Science, one of the cardinal rules of software engineering we were taught was - "Never Never Never destroy user data! Don't even touch it without first backing it up (for the user also) and be ready to restore software and data if anything goes wrong.
Oh how true.
While this update shouldn't destroy data, the fact that it prevents you from reverting to your old setup if something goes wrong -- is almost as bad.
But you can not revert, it is impossible. The new version of Th can not work with the old config. You have to revert the program as well, which needs some sort of backup.
Yes, before doing the automated conversion the program should warn the user of what is going to happen in case he wants to abort and make a backup. No! I have to disagree, the user does not necessarily know what needs to be backed up. There are perhaps obvious data files, (in this case those files in the TB profile directory) but what about other places data might be stored? Databases? Configuration files under /etc? /opt? etc.
There are none. And it is documented, I'm almost sure. Similar to this:
<https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer>
Well yes, but how does every user happen to know for sure? With absolute confidence? How does every user happen to know even that something written about thunderbird on a site hosted by something called mozilla might be reliable?
Because every admin knows they are related.
You're presuming far too much knowledge of every user. Marc is right.
In Linux, there is an admin who must know. If not, hire one. -- Cheers / Saludos, Carlos E. R. (from 15.3 x86_64 at Telcontar)
