How to import Thunderbird profile from newer to older version, thunderbird --allow-downgrade

After installing Linux Lite, I decided to import all my emails and contacts to Thunderbird.

After launching Thunderbird I received the following error message.

If you encounter this issue yourself, close down Thunderbird, open your terminal and enter the following command.

thunderbird --allow-downgrade

Ensure you have a back up of your existing email profile before running the command above.
