Thanks for the fast reply. I guess your one of those kind MVP guys.

The issue I have is with regard to Single Instance Storage. Most
people say that its crap, however I looked up the SIS ratio by
following a website and it was 12:1. In other words 40Gb file server
turns into 120Gb when either exported to PST files OR imported into a
new ORG.

I have a new org, and did'nt (can't) move all the old crap so was
looking at PST as an option.

I was wondering what others would do

B.T.W I have 2 orgs on 5.5 and one new 2003 org. None are in the same
site
