Transfer VMDK disks to new server in Vsphere 6

We have a Windows Server 2008 R2 file server that has 7 drives attached. We built a new Windows Server 2012 (64-bit) and would like to move the drives to the new server. We used to detach the RDM drives and reattach them, now we are not able to do that. What is the safest way to do this?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Where are the RDMs ?

do they still exist ?

You should be able to connect the new VM Hosted on the ESXi 6.0 server to the RDMs.

We converted the RDMs to VMDKs so they no longer exist.

Okay, if you've already converted the RDM to VMDKs.

Then just upload them to vSphere (ESXi) 6.0 using the datastore browser. (vSphere Client or Web Clent).

You will get other replies stating use WinSCP, of Veeam FastSCP, but to be honest with you the transfer time, is about the same for all of the tools.

A much quicker way, would be to put the VMDKs on an NFS share, and connect the vSphere 6.0 server to the NFS share, and then copy them from NFS to VMFS datastore on the server.

But by the time you have copied them from Windows CIFS server to NFS Share, and NFS share to ESXi datastore, the copy would have finished uploading using Datastore Browser.

It would have been quicker in hindset to complete a P2V....., and then discard the OS disk, and connect to 2012.
