Hi All,
We are planning the Exchange 2007 server decommission (10 servers) after a successful migration to Exchange 2013. Due to legal requirements, we need to mantain during 3 years a mailbox database backup of Exchange 2007 in a tape, in case we need to restore a mailbox.
1. What is the recommended environment to achieve this (excluding 3 party tools)?
- Mantain the last Exchange 2007 Mailbox server to perform the recovery?
- Install a new Exchange 2007 with a new DC in an isolated environment? In this case, must the DC be a clon of a DC in production or can be a clean DC?
2. Can I safely decommission all Exchange 2007 servers? Once uninstalled Exchange 2007 servers, could be installed at least one in an Exchange 2013 organization?
Thanks for your ccomments!
