I have 1 OD Master and 3 replicas. The replicas are in different
offices around the country connected via site to site VPN – all 4
servers are running 10.4.11. I want to start upgrading to Leopard. I
understand I cannot mix Tiger and Leopard servers as Master/
replicas. I will upgrade the Master first, but what happens in the
interim – I can’t possibly be in each office at the same time – or
even within days of each other to get the replicas upgraded... I
don’t have the option of having someone else do the upgrades.
I’m wondering what is my best course of action. Will I have to
demote the replicas to stand alone and not use LDAP while I’m
waiting to upgrade? Will the LDAP cache on the replica continue to
work in the interim but not receive updates? Will the Master be
horribly affected by having the 10.4 replicas waiting to be upgraded?
Any insights anyone has will be greatly appreciated. I will be in
one of our most remote offices next week so if I need to prepare
that server in some way for the coming Master upgrade, now would be
a great time to do it.
