Greetings,
I am planning to upgrade the existing Exch2007 to Exch2013.
The current setup is on Exchange 2007. However, I have legacy Exchange 2003 servers in my environment which doesn't hosts any mailbox(s) on it.
Please let me know if I have to decommission these Ex2003 servers before proceeding with the installation process to Exch2013.
Also, let me know if I have to use the same account used to install/configure the Exchange 2007 OR I can use any account having Schema Admin, Domain Admin and Enterprise Admin permissions to start the installation/configuration of Exchange 2013.
Thanks in advance !!
