We have two separate VCenters one on 5.5 and 6.0 with horizon. We need to add new hosts to the cluster and have everything on the VCenter 5.5 vm's all moved to 6.0 VCenter with horizon? Can this be accomplished or no? The new hosts are running 5.5 U3. and the old hosts are running 5.5.
the storage is the same for 5.5 vcenter and 6.0
As per below you have separate network for iscsi , but since you confirm same storage make sure the luns are visible on new host also .
if not configure to new host or as said previous follow that , connect host , power off vm , do vmotion (host and storage)
