Migrating from [very] old Thunderbird to current version
I've been using Thunderbird for many years. My current version is 45.2.0. My computer runs Linux Kubuntu 15.10
So yes, it's ten years old and it's showing its age. I have a new box I built, and have Kubuntu 25.04 installed. It installed the then current version of TB. I have yet to set things up, but migrating is a priority now.
Some solutions say (on ubuntu/kubuntu) to just copy the directory "/home/username/.thunderbird/profile.default" from the old to the new box. I would likely do it by zip, rar or ssh transfer.
If I do that, when opening up TB on the new box, does the data get converted? and if so, is it automatic? It seems to me that after then years, the data format would have some changes.
I'd appreciate any insight on this. Thank you.

You're right, some settings and files have changed though the years. I am not familiar with all of them, but I do recall that the addressbook was converted from mab to sqlite in ver 78. To bypass 78 would force user to use the import tool. This URL may be useful for you:

Thank you. I'll dive into this and hope it works.
