Yes, never upgrade in this way.

You are still using the old database.
Set up a new computer running either Debian, Ubuntu 18.04 or Ubuntu
20.04. Install Samba, either using the distro packages or Louis's
packages from here: http://apt.van-belle.nl/
Then join the new computer as a DC to your original DC. Once everything
is running correctly, transfer the FSMO roles to the new DC, then demote
and turn off the old DC. You could then upgrade the old DC.
