Migrate Thunderbird from 15.1

I just made a clean install of LEAP 15.2 on a separate partition and want to migrate my LEAP 15.1 Thunderbid configurations. Now I could copy my entire home .thunderbird directory with five separate accounts but I am sure there ia a lot of accumulated garbage that I would prefer to leave behind. What are the necessary files I need to move? Internet searches seem to only refer to the Windows methods.

Thanks in advance

As far as I know, everything important is in “.thunderbird” (a directory) under your home directory.

If the old place is on a mounted disk, you can probably just use a symbolic link. Otherwise you would need to do a recursive copy.

I did a very similar migration last year, at the time these were the files that were not needed:

There are also some sub-directories in your profile directory you could remove completely, they will be recreated as needed:


Initially I moved, rather than deleted them, as they took up such a small space I later decided to just leave them.

Since then there may be be other files that are redundant, a good indication is the last access date, although that’s not always reliable.

Thank you Tannington, that cleaned up a lot.

Assuming a separate home partition, what I do is install the new OS on it’s own partition without mounting home, Test the new OS until I’s satisfied then simply mount the old home. This is the main plus for having separate home partition rather then the “new” way of having all on one partition under BTRFS. You can remove the test home by booting in safe mode and removing the contents of /home that is on the root partition.
