[CentOS] Transferring Thunderbird mail accounts: Windows vs. Linux

Hi,

One of my clients brought me his PC with Windows 7, so I can migrate it to Linux, e. g. CentOS 7 + KDE. So far I made a backup of all the data, but I wonder how I can migrate the existing Thunderbird account.

An operation I perform quite regularly is replace an existing Linux system (Ubuntu, openSUSE, Fedora, whatever) by CentOS. When Thunderbird is configured, I just backup the whole ~/.thunderbird directory and then restore it on the new installation, which usually works perfectly. Any idea if I do this when moving a desktop installation from Windows 7 to CentOS?

Cheers,

Niki
