Restore CE v6.3 and upgrade to 7.1 - ubuntu 20.04 - ccnet/seafile.ini


I’d put off upgrading until I upgraded the machine that the server was running on. I was running CE 6.3 on Ubuntu 18.04. I made copies of the seafile-data and the three databases as specified on the backup/recover instructions, and have copied these files back and reimported the databases.

When I try to run the script bash
I get an error message /home/seafile/ccnet/seafile.ini not found. Now quit

I tried to reinstall 6.3, but was struggling with the python 2.7 dependencies which appear to no longer be easy to fix, notably python-mysqldb appears obsolete

How could I generate this ccnet/seafile.ini file or otherwise work around to keep the backup?
