We want to start migrating our 8.5.3 servers to 9. Unfortunately, the cookbooks and information that isn’t beta are pretty hard to come by. I upgraded my dev server and it was easy and done, but I have a Sametime server, a Traveler server, and a WebSphere/iNotes server in production. Does anyone have any helpful information to make sure and watch out for when upgrading these types of servers? Or have some decent links with information I can read up on?
