We just acquired a new company and we’re looking to put them on our network. We installed a router at their site and it’s live. MetroE 10MB line and backup T1 MPLS up and functioning. I can ping devices on their network now.
The new company and ours are both are using Windows 2003 Active Directory and Exchange 2003. We need to move their email accounts to our server, but they still need their autonomy to the outside world…like an SMTP with they old email address, yet on our Exchange server. I'm looking to migrate the users slowly, not all at once.
What’s the best way to accomplish this?
1) Email – They have there own email server, but we want to migrate them to ours, yet still allow them autonomy by creating them an smtp. How do I go about doing this with their email server still up and functioning for users. Can i create an smtp on ours and still have it on theirs also?
2) Is it possible to migrate them slowly to our mail server?
3) Can we have some users migrated to our server and some not, but each receiving email from their own old domain, such as....Example email@example.com and this user is on ther old email server. and have another user on our email server with an smtp firstname.lastname@example.org?
Hope this makes sense
