Is there a way to take an existing install of SBE 2.5 (with Simba) and inplace upgrade to the NOWS SB 11 edition?

If so, how much of a pain is it? Does it require to remove the SBE (simba)? Does that break anything or everything?

I wish I had known that Novell was going to go this path, and allowed for the separate installs on version 2.0.
If it was available as standalone installs on version 2, shame on me for missing it.
