Hey Everyone,
I've inherited some rather unmaintained servers as part of a new job and I'm looking to get them all up to date.
We have a server for auth for satellite services that uses slapd/openLDAP. It's on a rather old version, and I'm wanting to upgrade it.
I would like to see if anyone has advice on how to upgrade from Ubuntu 18.04.6 with the current 2.4.45 slapd/OpenLDAP to Ubuntu 24.04.
I've looked around to try and find guides that show upgrades notes between versions but haven't found anything relevant.
Hi Justin, the admin guide[0][1][2] has information that outlines the usual steps and details on what configuration options might need special care.
If you have a replicated environment, you can upgrade servers individually or introduce new servers into the cluster and retire the old ones when you switch your live traffic over to the new ones.
