Below is my environment
2008 R2 DC1 : John.com - Primary DC
2008R2 DC2 : John.com - Secondary dc
2007 Exchange server : john.com
Now i need to change my domain from John.com to Mike.com
what will be the suggestion?
Should i need to cross forest migration from John.com to mike.com or I can change the domain name ?
Once I will change the domain need I need to migrate all mailboxes from John.com to mike.com in office 365.
and I need to remove john.com from my whole environment.
What will be the best practices? Kindly suggest...
