[Samba] Upgrading 2.2.8 -> 3.0 howto, pitfalls?

We have two production servers running Samba 2.2.8 on Redhat 7.x 
using XFS filesystem with ACL and quota support. Although it has been 
working ok for nearly two years, we still see strange ACL behaviours, and 
occasionally what appears to be winbindd idmap corruption. PDC is NT4, 
and samba servers are domain members only.
We're also seeing lackluster performance at times, possibly due to the 
number of concurrent users, typically 100, but peaks of >300.

I'm hopeful that 3.x might address some of these issues, but am 
concerned with transition problems on heavily used servers. Specifically, 
where can I find answers for:

1. Is the winbindd idmap unix-domain mapping table migrated smoothly?
2. Are the memory requirements similar to 2.2.8? (we're running 512Mb, 
which seems to be just barely enough for 2.2.8).
3. If things go wrong, can I just restore the idmap and 2.2.8 files and go 
back?

Thanks
