How to fix Conflict vibs error ESXi host upgrade from 5.5 to 6.5?

I got  an  error  while  upgrade ESXi host  from ESXi  5.5 to  ESXi  6.5 . The  upgrade  process failed with  the error  “Conflicting_vibs Error” which explained  at the  picture  I added.

At this  KB  I explained  how to fix  this  error.


Error: <CONFGLICTING_VIBS ERROR: Vibs on the  host are  conflicting  with  vibs in metadata.Remove  the  conflicting vibs or  use  image builder to create a  custom  ISO  providing newer version of  the  conflicting vibs.

Login  ESXi Host  Over  SSH

~ # esxcli software vib list|grep Mel
