Hello,
I have the following setup:
new domain: test.local
complete new domain with new user accounts has contact with the old via trust relationship.
old domain: company.local
Has 2003 Server OS and Exchange 2003 installed on it.
Our It manager wants to setup a way that all mail is deliverd to the old and the new mail server.
The already existing mail will be imported via a tool or simply exporting via pst.
The reason they want this that they want to be able to fall backup to the old exchange if something goes wrong.
And to be able to migrate user account per account (small company) and see if anything goes otherwise wrong.
Is this possible and without downtime and other issues?
Kind regards
Jo
