I was surprised to see those points together. I definitely agree on the 
16 GB (or more--we use 24 GB) per mail store. But running 5 or 6 
mailstores just for 3,300 accounts? Is a digit missing from the number 
of accounts?

I'm also curious about what sort of issues you expect; maybe someone in 
this group can offer advice. We upgraded from 5.0.16 to 6.0.3 a few 
months ago and it went well. Usually for upgrades we keep the system 
running as much as possible during the upgrade, but for that one we took 
the entire Zimbra cluster offline. It ended up going fairly quickly.
