Hi, I have two SharePoint 2010 farm, one is Production and another one is development.
I am restoring one Site collection via Database restore method (size is 60 GB) two times on Development farm.
first time DB is restored as DB1 and attached DB1 with new Web application "WA1" and then site is up and running on development farm.
But second time when I restored DB as DB2 and try to attach this DB2 with another new Web application "WA2" on same development farm then getting error of same guid, I also try to assign new guid to DB2 database in attach command but site collection number showing 0.
I cannot run STSADM or SP PowerShell command for backup and restore because site size is 60 GB.
Please guide me how to restore
