Hello,
We are running a (small) number of OpenLDAP instances with v2.4.58.
There is a single master and 4 syncrepl consumers (all on CentOS 7 boxes), all running with back-mdb.
We are planning our migration from 2.4 to 2.5.x
My question: Would it be OK if we migrate our master server to 2.5.latest, and leave consumers to 2.4.58 for a while? Would any implications be expected?
I would wait for 2.5.5. Other than that, replication is a protocol level bit, so it works between 2.4 and 2.5 w/o issue.
Finally: Is there a script or other way to check possible config incompatibilities with 2.5.x (in order to avoid surprises)?
Have you read the upgrade appendix of the admin guide?
