You are right.
If I did as you say and I say and back up every day, I would be OK.

Then I could have done it again and again until I figured out the
purpose of the .migrated file.

"This file is automatically created by /usr/bin/thunderbird, it will be
created on every start of Thunderbird if does not exist.
Remove that file only if you know the propose of this file."

In my case of stupidity the backup was a week old, the cat laughed too.
I probably should have added the .migrated file before I learned of it
post script. (-;
