my environment is not straight forward for migration thats why please check mybelow text:
Current Status of XYZ Exchange Organization
Xyz Exchange organization contains :
1.two Back-end servers Mail101 and Mail202 running exchange 2003
2.Each one of the Mail servers is a two nodes cluster as shown in slide number four
3.One front-end Server F-end02 running also exchange 2003
Current status of xyz Domain Controllers
xyz has 2 windows 2000 server domain controllers DNS03 and DNS04
There are another 3 domain controllers running 2003 server
DNS03 is the PDC and Operation Master.
Why to have new Server?
¡Mail101 has been running on windows 2000 server, this server is not performing good anymore because of the old hardware and also because of old operating system.
¡The new server Mail303 will be replacement for the Mail101
Platform of new Mail server
¡New server Mail303 also will be a two nodes cluster running windows 2008 server on a new hardware
¡This new server should be running exchange 2010
¡All Mailboxes in Mail101 should be moved to this new server and Mail101 will not be operational anymore
The Exchange installation and migration from old server to new exchange 2010 server.
