One approach to minimize downtime, assuming CPU from the old and new cluster are compatible, is just remove the old ESXi 5.5 from the vCenter 5.5 and add to the vCenter 6.0.

The procedure is here: Moving a managed ESXi/ESX host from one vCenter Server to another vCenter Server (1004775) | VMware ...

After add the old host on the new vCenter, you can migrate the virtual machine to the new hosts.
