Simon,
We have extended the migration section in the documentation
https://www.knot-dns.cz/docs/2.8/html/migration.html#upgrade-2-7-x-to-2-8-x
Probably, it's your case.

Hi @all
I was trying to migrate knot to a new server with Ubuntu 18.04 and knot
2.8.0. I managed this by just copying the content of /var/lib/knot/*
from the old to the new server.
One of my domains threw an error when starting knot:
knotd[5186]: error: [<zone>] zone event 'load' failed (malformed data)
keymgr throws the same error. I dumped the data out of the 2.7.6
installation with mdb_dump and imported it into the 2.8.0 installation,
which did not help.
I then uninstalled 2.8.0 on the new server and installed 2.7.6,
migrated
data from the old server with the same procedure and it worked, no
errors.
Just out of curiosity I upgraded then the new server from 2.7.6 to
2.8.0
to see what will happen: It was the exact same behaviour, the zone
couldn't load.
How can I proceed here? There is obviously something wrong that the
update breaks the loading of the zone. Is this on my end or a bug in
knot?
Thanks
Simon
