I have a 2008 R2 Server that I need to upgrade to Server 2012 Datacenter. I know upgrading is not recommended but wiping this server and starting over would be a total pita. Problem is that the server has 96GB of memory and only 100GB free on C: (total of 130GB). Windows won't install because it says it needs at least 99GB of free space on C:. So I decrease the page file enough to get to ~103GB free and run the upgrade again - now it says it needs 111GB! I assume this has something to do with the amount of memory/page file settings. Could I just remove the ram down to 32GB, then install, then re-install the rest of the ram?
