ESXi

I have a 3.5 ESX host with a single VM on it that has a 3TB RDM. 3TB+ RDMs were not supported but worked under 3.5 but didn't on 4.x so this host has been sitting there at 3.5 for a while for us. Now that we've upgraded our prod to 5.0 I'd like to migrate this VM over from 3.5 to 5.0 with its 3TB RDM. Anyone think this would be a problem?

Assuming the new 5.0 hosts have VMFS datastores I can't think of any issues with this, but it might be worth giving this article a quick once over;

if you are just moving over the iscsi/fc mapping it should be fine.
