Migrate VM from Vcenter 5.1 to 6.

Hi,

I have been tasked with Setting up New Vcenter 6.0 to replace current 5.1  Vcenter.

Currently we have 6 ESXi 5.1 Blade Cluster on Vcenter 5,1, I have setup a new Vcenter 6.0 and 4 New Blades with ESXi  6.0,

What is the best way to Migrate VM;s from Vcenter 5.1 to Vcenter 6. 

Here is what I was planning to do,

Remove (disconnect ) ESXI host from Current Vcenter 5.1 Cluster and add it to Vcenter 6.0 and then to the VM Host Migration.

Any suggestions will be greatly appreciated..

Thanks
