Need to rebuild MSSQL server back-end

Hi,

I installed OpManager build 8720 and the NFA plug-in on a server and attached them to another MSSQL server. On the server where I installed the MSSQL I also installed the DeviceExpert.

Unfortunately the customer needs to format and rebuild the MSSQL server from the scratch. How I can procede?
I thought to:

- backup the OpManager and NetFlow DB: how???
- backup the DeviceExpert DB: how???
- stop the services on both the servers
- the customer rebuild the server from the scratch: Win 2008 + MSSQL Server 2005
- install DeviceExpert on the new server
- restore the OpManager and NetFlow DBs: how???
- restore the DeviceExpert DB: how???

Is it possible??

Thanks for your help
Regards,
