Need assistance in upgrading VMware Update Manager 4.1 into 5.1u1 ?

Hi,

Can anyone here please assist me with the guide or steps by steps implementation for upgrading the Vmware Update manager safely from 4.1 into 5.1 ?

Does it requires Vcenter downtime ? can this be done in business hours ?
Does it automatically update something on the ESX / ESXi hosts which could affects production VMhost operations ?

Thanks in advance

The step-by-step guide can be found here.

Please check compatibility with your environment first here.

As long as you do not need to upgrade vCenter it will not require downtime. I see no reason that this can not be performed during hours, but there are always risks involved in any upgrade.

The upgrade process will not do anything to effect your production hosts. However, your previous scheduled remediation rules will still be in place so you may want to double check those.

ok big Daddy, I was just worried that if the previous set schedule is overwritten or lost somehow it would be a headache to configure it for all of the data centers.

So basically during the inline upgrade it should work without issue at all wit the ESX/ESXi hosts ?

You should backup your current update manager database just in case anything goes wrong. This way you can always uninstall 5.1 and reinstall 4.1 using the restored database.

The upgrade only makes changes to the vCenter server and the update manager database. It does not make any changes to the ESX/ESXi hosts.

ok, I have seen in the page: http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php?

Does this means that by using VMware Update Manager, I cannot upgrade my currently running ESX & ESXi 4.1 into ESXi 5.1u1 ?

I believe you are looking at it backward. You can upgrade 4.0 - 5.1 to 5.1U1

thanks man, does it have to be two steps upgrade or just one step in a single reboot process ?

I'm not sure I understand your question. However, the upgrade should not require a reboot as it is separate from vCenter.
