I'm planning to update soon, and I was wondering.
Is there an issue with running 10.3 at one site and 11.3 at the other for few weeks, or do I absolutely have to plan updating both sites (and all clients) simultaneously?
Right now, I have all emails coming into one site, and routed when necessary. I also have public folders replication, and single system contact list.
Any issues running different versions on different sites?
Thanks.
