For some years I have transferred the current Thunderbird data profiles from a desktop computer to a laptop once a year when traveling. When returning home six months later I have been able to delete the old data profiles in the desktop and transfer the 'current data' from the laptop over. This system has worked for some years however after recently upgrading the laptop to the latest version (140.2.1esr) and installing the latest version on the desktop (both 140.2.1esr) the transfer of data fails. The program identifies the data on the laptop as an "old program". Could someone point me in the right direction and advise where I am going wrong at the moment. Thanks in anticipation , Bruce
