Exchange Migration Data restore

Hi Guys,

We use Networker 8.2.3 with NMM 8.2.3

Recently we have migrate Data from Exchange 2010 to Exchange 2013 upgraded Server from Windows 2008 to 2012. Standalone

I have a question about the Data backup.

If we need to restore Data from previously from the date of migration how can I do?

Because everything from the old server is not more useful.

Does anyone of you had the same problem?

Thank you.
