I used the CLI method to upgrade my hosts from 5.5 to 6.0 because it was actually easier than using Update Manager, even though I administer a medium sized environment.
After the upgrade (which was super smooth) I now show the following:
ESX/ESXi Version: VMware ESXi, 6.0.0, 2494585
Image Profile: (Updated) ESXi-5.5.0-1746018-Custom-Cisco-22.214.171.124
Is this a problem (other than bugging me that they don’t match)? And is there any way to resolve this?
Should not be an issue, You should be able to use that image profile to roll back too.
"Image Profile: (Updated) ..." displays the image profile used when you first installed ESXi on the host, i.e. not necessarily the current version/build, so don't worry about this. Anyway, if your hardware as well as any 3rd-party software (e.g. backup) supports the latest build, I'd recommend you consider updating to ESXi 6.0 Update 1a asap to avoid known critical issues (see e.g. VMware KB: VMware ESXi 6.0, Patch ESXi-6.0.0-20151004001-standard).
