Give support a ring, they can probably figure what is happening and get it going.  It's very rare I've ever seen an upgrade fail or not be able to recover worst case from it.
I am running vFoglight ver 6.7. recently I have added 2 new ESXi 5.1 Host and 2 Datastores in my vsphere cluster. These new stuffs are not appearing in vfoglight under VMware environment dashboard. I tried to refresh the added vCenter server by re activating it. No success. Could anybody help me how to get it up to date.
