Hi all, I already suspect the answer might be *no* because I'm looking for an easy way to migrate from E2K to E2K3, and when it comes to Exchange, nothing is ever easy!! Can I mount a store taken from the E2K setup on the E2K3? Can I use RSG instead and move mailboxes? The environment will be new W2K3 AD populated via ADMTv2 for the lovely siDHistory! All tips and comments gratefully received ;-) TIA, Rich.
