we are a global company with multiple location (US, Canada, Europe and Asia) (500 users)
currently running exchange 2003 enteprise ( 6 total exchnage servers located accordingly ) on windows 2003 AD.
the question is:
we would like to deploy E2007 in the US only by Virtualizing Exchange with NetApp and VMware, that being said for all cost and pratcical reason we would like to keep our E2003 in (Canada, Europe and Asia) intact without upgading them (at least initially)
Question: does this sound like a doable scenario or just a fantasy ? if doable what are the pros and cons ?
