Migrating Thunderbird from Win7 Pro to Win10 pro fails. The usual method of saving the config folder from [user]\Appdata\Roaming isn't working. Have tried various approaches including the profile tool, moving Local and Roaming data in full, retaining existing profile and moving Roaming files, etc. Same result every time. Thunderbird behaves as if there is no email config at all, BUT the address book does carry over. No accounts, no folder, no emails. Version on both machines is 60.7.0 (latest release).

The account has numerous folders, huge Sent folder (3+GB), nothing really unusual but it's effectively an archive going back years, in constant use and vital for the user. Must solve this!

I've migrated Thunderbird scores of times in the past with no failures or major issues ever. Something has CHANGED.

Did you copy the Thunderbird folder according to the exact instructions given here?

Make sure TB is closed and not running in the background when you do the transfer. On the W7 computer, right-click the Thunderbird folder, Add to zip, then copy the zip file to W10, delete the existing Thunderbird folder in Roaming, extract the zip.
