Hi,We are having SCR cluster setup, which hold 4 cluster servers and 2 hub servers. And we do have seprate test lab environment with single server which have mailbox,hub role.Now, my questions is: how to move one of the production db to test environment?ThanksFunnyghost

Is the production database in another forest? You cannot take an Exchange database and move it outside of the forest. Database Portability http://technet.microsoft.com/en-us/library/bb123954.aspx

I checked the Database Portability. We have the same Exchange/Windows version in lab.Funnyghost

Its not about the version of Exchange and Windows, its about the Forest. If you have a duplicate of your existing AD Forest/Org in the lab, then it will work. Otherwise, you will have to manipulate legacyexchangedn values. It can get messy, but that will work as well.

We have the duplicate of our existing AD Forest/Org. But how I can move one of the production DB to lab environment?Funnyghost

If you have a true duplicate forest in the lab, you can do a redirected restore from your backup server or simply dsimount and copy the database from prod to the lab, or restore to a RSG in production and then copy the store over to the lab.

Yep, I did the same thing which you suggested and it works.ThanksFunnyghost
