In general it is never safe to upgrade without testing. Upgrading from
2.1 to 2.4 I wouldn't expect too many interop problems with your LDAP
client app though provided you know what you're doing.
But when using multi-master replication you should be aware of some
issues with data consistency when doing load-balancing/automatic
fail-over between the replicas during several write requests.

Whether there is any issue with multi-master replication highly depends
on the nature of your data and the behaviour of your application.
