This has to be a FAQ, so I apologize in advance for my inability to find the answer myself...

We have an old version of Zimbra:
Release 5.0.8_GA_2462.openSUSE_10.2_20080709173037 openSUSE_10.2 FOSS edition

I would like to bring it current. Do I need to step through each interim version to do this? Are there special things I need to know?

Thanks very much for any tips and pointers you might provide.
