It is not guaranteed it’s going to work among different computers, OS and Thunderbird versions.
I have exported the profile folder from Thunderbird running on a Linux machine and then tried to import it into Windows 10.
It simply didn’t work. No messages, nothing, in spite of the folder size being +2GB in size. The import wizard ran to the end and confirmed a successful importation of data.
Not really. After restarting Thunderbird, there was nothing in there to see. No messages.
