Is it safe for me to run the upgrade from VMWare image for 6.7 update 2 to the Dell custom image for 6.7 update 2 ?
First of all , do a backup of your ESXi configuration.
To answer to your question, i would say yes, the differences between VMWare and Manufacturer custom image is about drivers.
I lived the same issues with HPE servers and i didn't have any problems while update from vmware image to HPE Custom.
After the upgrade just do an Update Manager Scan from your vCenter to check if inadvertently some drivers, patches, or extensions miss to your ESXi to be fully compliant.
Let me know how it runs
Thanks for the reply. I'll give this a try as soon as get a min
Did you succeed ?
This post definitely came around the right time for me. Going directly to Dell's website with my hosts service tag number I was able to download the correct 6.7u1 iso. Hope OP was able to get his issues resolved.
