As i am doing transition from Exchange 2007 to Exchange 2013.
Do i need to create an Host Record(legacy) pointing to my exchange 2007.
After i decommission my exchange 2007 i will change the ip of my exchange 2013 back to the old ip(exchange 2007 ip)
If i create the legacy host record do i need to delete this record as i decommission my exchange 2007.
this legacy record should be pointing to my internal ip or the public ip.
do this record should be created at the ISP also.
Should this record be added to the SAN certificate
should this record be added to %systemroot%\system32\drivers\etc\hosts
