Our goal is to migrate our file server to newer hardware. We are in an Active Directory Environment 2008. Our existing file server is a Windows 2003 stand alone file server with about 10 LUNs ranging from 10GB - 600GB with storage provided via an HP EVA 4000 using fiber HBAs. The new server is a Windows 2008 x64 stand alone server that is also connected to the EVA via fiber HBA.
The data included on this server ranges from Active Directory user profile directories, department shares, imaging system images and apps, etc.
In the past when migrating to the existing solution, we simply robocopied data from the old location to the current file server connected to the EVA, preserving file security, however now we have this great and powerful option to migrate the data simply by redirecting the EVA LUNs to the new file server, so there is no need to physically copy data. However using this method will not migrate the security.
So, my question is, has anyone migrated a Windows-based file server in this fashion, LUN transfer, and if so is there an easy way to migrate the file security other than manual?
