we are upgrading from 5.5U3 to 6.5U2 ... have done the PSC to VCSA already but while running the migration assistant on vCenter, we are getting warnings that our third party DVS (from Cisco/VM-FEX) API will not be supported on 6.5U2 ... researching this I guess the VMware is no longer supporting the third party APIs. So as a consideration, can I proceed with the 6.5U1 upgrade on vCenter so that it can support the third party Cisco API with the PSC already at 6.5U2?
Any input/direction greatly appreciated.
