Moving the old driver from the old cluster to a new standalone server will work just fine, provided that the SQL Server instance version is identical.
The easiest way to do this is to present a new temporary LUN to the new server with the same drive letter as the drive which hosts the master database on the cluster. Install the instance on the new server configuring the master database to be in the exact same location as it is on the cluster.
When you are read to migrate, on the production server stop both SQL Server instances. Remove the LUN from the new server. Attach all the LUNs from the cluster to the new machine. Start the SQL Instance on the new machine.
If you are moving from a Windows 2003 cluster, and the disks were first setup on a Windows 2003 clustered machine you should create new LUNs and robocopy the files to the new LUNs. Windows 2003 when clustered wrote a clustered disk information which isn’t always compatible with non-clustered servers.
If you are going from Windows 2008 clustered to Windows 2008 non-clustered you’ll be fine.
