ESX 6 to 6.5 Conflicting_Vibs error - Fujitsu RX

Hi!

I recently successfully updated a single Fujitsu RX350 ESXi from 5.1.0 to 6.0 Update 2. When trying to upgrade from 6 to 6.5 following error appears:

CONFLICTING_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 versions of the conflicting vibs.

"Emulex_bootbank_scsi_lpfc820_8.2.4 151.65-1OEM.500.0.0.472560"

I already found a solution: simply remove the vib from the old system. If I understood correctly, then the command

"esxcli software vib remove --vibname XXXX"

removes a conflicting driver from the system? If I do that what are the consequences in this case? Does the setup still recognize the installed system and the datastore with VM's?

What if the setup fails - how can I undo that step?

Many thanks in advance!
