Apparently I don't know how to read and updated a server that was not on the compatibility list (R620 not R630). I upgraded to 6.7 and the last supported version was 6.5 U3. The only issue so far is minor but i would prefer not to keep it this way since VMware will not support it. Are there any issues with Going back to an older version of ESXi? I have 2 hosts that need this and if it's a good option then i will do it otherwise i will keep it like it is for a few months until the hardware upgrade. Any comments or suggestions are welcome. Thanks
