I'm preparing to upgrade a mailbox server in a multiserver setup where i have a mta serve,r ldap server and mailbox server. In fact, this is one of 2 mailbox servers and the rest of the zimbra system will stay up during hte process. I've been browsing the wiki article Network Edition: Moving from 32-bit to 64-bit Server - Zimbra :: Wiki but that seems more directed for when you have everything on one server.
If I try to do a regular install on the new 64bit server, I assume that wehn I point it to our zimbra-ldap server it will fail trying to create the server in ldap because the server already exists.
I am thinking of doing a install -s to do a software install only, then copying the localconfig.xml and all the license, store, mysql data over and then seeing what kind of errors I have from there.
Does anyone have any advice in this situation?
