If anyone knows where to submit a product feature request please let me know!
I have a need to upgrade my ESXi hosts from 4.x to 5.5 which works splendidly with VUM. However some of my servers are not compatible with 5.5 the highest they go is to 5.1 U1 then they drop off the supported list. Using vCenter 5.5 VUM I can manage any of my ESXi servers but in order to update them from 4.x I would need to go all the way to 5.5 VUM will not allow me to upload an ISO image for 5.1 versions any longer. I can still patch 4.1 and 5.1 hosts.
For the time I can do manual upgrades to the servers but who wants to do that? I'd much rather use the tools to handle that.
Regards,
Jeff
