We have a windows environment with one server acting as DC, DNS and also acting as ex server. We would like to demote this server. So we have installed a new server and all fsmo roles tferred to new server and also installed exchange server. Now i need to tfer all the folders and mailboxes but i have some more questions before i do that....Also I need to know is it advicable to run both exchange servers at the same time for some period until we transfer everything on to the new server and are happy with the performance of the new server?
1. Can I have my two exchange servers(old and new) running at the same time with both having some mailboxes and capable of sending and receiving emails externally??(I can ask my service provider to do the MX record pointing for the new server and also keeping) Once that is done on ISP side, Do i need to do anything on the server side to locate the mailboxes (whether the 'email' is for the mailbox resides in old or new server?)
2. If i have two servers running, how will the users access email from OWA (for ex if i type mail.mydomain.co.uk and entering my login details will automatically find the mailbox where it locates or do i need to do anything? Can I implement SSL on the new server from a third party (Verisign beforemaking the server capable of sending emails externally??
