Moving Large Profiles To Another OS/Machine

Created a new Ubuntu 24 something machine. Thunderbird was installed with SNAP. SNAP Sandbox Invalidates Decades of Tutorials on Migrating Profiles. Uninstall Thunderbird with SNAP Reinstall Thunderbird with apt-get

Try to Export on my Mac my 4 email account profiles to a .zip files. One of them is 38GB, so this won't work.

Try copying the the folders to a USB Drive and then moving them over to the user/<name>/.thunderbird folder.

Why can't I just drop them in there and then start thunderbird and it loads everything and doesn't ask me to provide a password for my email accounts? I mean wouldn't that be ideal?

What's the correct procedure?

Although I am a Linux newbie, these steps should work (although I've never used SNAP):

  1. click help>troubleshootinginformation
  2. scroll down to 'profile folder' and click 'open folder'
  3. note the file location. this is where your Thunderbird's default profile is.
  4. exit thunderbird
  5. copy the old profile to the same folder as the default profile
  6. start TB and click help>troubleshootinginformation
  7. scroll down to 'profiles' and click 'about:profiles'
  8. click the 'create profile button
  9. click next
  10. enter a short name for profile, such as OLDPROFILE
  11. click the choose button to locate and select the old profile you copied
  12. click finish and activate the profile
