I have Thunderbird 115.15.0 on win 10 dell xps desktop and want to install Thunderbird on my new win 11 Dell xps. The microsoft store gave me ver 128.5.2. I read that if I use the same version I can transfer my profile from the old computer. How should I approach this? Should I figure out how to update the win 10 machine to 128.5.2 before transferring the profile?
