Sorry Guys...Am posting this question again... While surfing the net i got this info from one of the Microsoft site which states that the exchange database can be restored in the different exchange server with same Org name and Structure in different forest. Here is the site http://support.microsoft.com/kb/823176 (have a glimpse at Method 3) Is it possible to restore an Exchange database from a backup in a different Exchange recovery server (with same organization name, administrative group & Storage group name) in a different Forest? Plz give your suggestions... and also let me know if any one of you have tried this and got succeeded....
