[Samba] Any pitfalls updating straight from 3.0.34 to 3.5.2?

[ray klassen]

Okay, so I've just put the sernet repo file in my yum.repos.d directory and a yum update will elevate my samba server to the latest version. Is there any pitfall that is out there that I can avoid before yum updating.

Centos 5.3
samba3-3.0.34-37 & related packages
openldap-2.3.43-3.el5 & related packages

I still have my samba3-3.0.34 packages squirreled away so I can force downgrade if I need to, but I don't want to if I don't have to.

Any advice before the plunge?
