Hi,
What would be the best approach to upgrade a multimaster setup?
Is it possible to stop node#1 (version 2.4.43), do the upgrade to 2.4.45 and
then start the node again, let it replicate (does the version mismatch matter?),
and afterwards do the same with node#2?
Or is it better to build a fresh environment with the new version in parallel,
get the data with slapcat/slapadd and switchover IPs?
Thanks in advance,
Christian

Christian,
There is an alert warning for MDB users who have multival-hi and
multival-lo configured. If you using these then a database reload needs to
be part of your upgrade plan. Otherwise, take one master down, perform a
backup using slapcat, update the software and bring it back up. Wait for
replication to catch up. Then repeat the process on the second master. You
should be able to avoid downtime and dataloss.
If you're going to the trouble to upgrade, why not use 2.4.46 which has
several improvements and fixes over 2.4.45. Just a thought.
Warmest regards,

This doesn't exist in stock OpenLDAP 2.4 (It's an openldap 2.5 and later
feature only).

Generally for upgrading OpenLDAP, you simply drop the new binary in place
and restart. If you use back-bdb/hdb and the underlying version of
BerkeleyDB has changed, then you will have to slapcat, upgrade the binary,
slapadd.
