I have a PowerEdge 2850 server, which when it was originally set up (by someone else) had Windows 2003 R2 on it. However, when they set it up, the partitioned the C: drive with so little space that it's run out of space. We've gotten a newer server from Dell and I've turned that 2850 off. It's been off for a month or so.
But I would like to repurpose it as a backup database server. Can I install Windows 2008 R2 Server on a PowerEdge 2850?
