Hi,
Exchange server is on exchange 2003 on windows 2003 R2.
- I had an architecture of parent & child domain controllers, Where parent company is closed Down. But we have an additional Domain Controller of parent DC in our premise.
- Due to this fact exchange organization is also unavailable & cannot make modification on my exchange server configurations (Global Settings, such as changing recipients attachment restrictions, everything is grayed out).
- Is there any way where we can have staged migration. I mean can I keep old & new server running together & keep few users on new Exchange organization & rest of them be on an existing server itself. (I tried testing this too, but email delivers to mailbox store, so, it checks a name & say “Mailbox not available”)
- If I create a new domain environment, I have challenge of migrating users (This I can achieve with ADMT, but actual story starts with mailbox migration)
- Real pain is, I have more than 500 users, can I achieve direct migration over a weekend. (few are POP & OWA users, around 50)
Can anyone help in this please.
