Last Friday I managed to put a new CAS box in place of our old one, and as near as we can tell most things work, but it looks like at least in some cases ActiveSync devices don't take the push sync unless the profile is removed/re-added (I just heard about that issue this morning).
My main question is that I've been asked to build a 2nd CAS box to make an array and can I just remove/reinstall Exchange 2010 on the old CAS box (by "old" I mean former, as it's a VM with the same hardware /specs as the new one). The old CAS box has the hostname/IP that non-Exchange systems used to SMTP relay (we're not yet sure if all the miscellaneous systems have been repointed). It turns out the reason my team wasn't able to patch the old CAS was because SP3 for E2K10 would ask for the location of various installation media, and pointing it to the knows E2K10 install locations/files, it would simply re-prompt for the location of said files. Ideally I'd like to have a CAS server with the same IP/hostname of our old one for comfort's sake, I'm just wondering if 1. It wise and 2. If just removing/reinstalling Exchange is the best way to achieve it. Dave
