This is the first time I've tried using update manger. I have a mix of 4.0.0,24438 and 4.1.0,348481 ESXi servers and I want to upgrade them to 4.1u2. I've tried downloading the upgrade bundles and isos and they all fail on various points like the uploaded upgrade is not a valid upgrade package, checksum error, etc. Can someone tell me the process I need to go through to get these updated to 4.1 Update 2? I'd also like to use the Dell OEM version of ESXi 4.1 to upgrade if possible.
Thanks in advance for the help.
