This is actually the reverse, this is hope :-)
If the server is still working on Samba 4.3 after the failed upgrade
attempt, this is a way forward to upgrade over DRS instead.
Arnaud, I would be very interested if you could attempt to instead
upgrade using a replication based approach, and if that fails, to try
the patch at:
https://gitlab.com/samba-team/samba/-/merge_requests/2728.patch
It would be very valuable to me to get real-world feedback.
To test in a 'no changes' approach, you can attempt replication without
changing the domain by running 'samba-tool drs clone-dc-database --
server $SERVER --targetdir=$SOMEWHERE_SECURE -Uadministrator'
We can also look into why the in-place upgrade fails.
Running 'samba-tool dbcheck --reindex' using the modern version should
allow the error to be seen in a more controlled circumstance, and allow
raising the debug level etc.
It is a large version jump, but we actually do keep old databases
around in our selftest to test this, but it is hard to trigger the
variability of the real-world.
I do wish you all the best getting to a modern Samba version.
