On a 64-bit server (IIS 6), can I run some asp.net apps as 64-bit and some as 32

I know I'm not supposed to mix the bitness of processes, but don't application pools isolate processes (if in isolation mode)?

I was thinking I could create two application pools, one that has the 32-bit apps, another that has the 64-bit.

Is this possible? (I've never worked in a 64-bit environment before, so I'm totally clueless)

thanks for any help!You'll probably need to migrate. Have a look at the set of links here: http://blogs.msdn.com/frankred/archive/2004/12/01/273176.aspx
