vCenters 5.1U1a upgrade question

[vmhelp201110141]

Hi ,

We have  five vCenters  and all are  registered in same  SSO Server. Now  want to upgrade my vCenters  from 5.1 to 5.1 U1a. What was procedure. Is it possible do  upgrade one by one?

Below plan will work?

1.Upgrade  the SSO server first

2.Upgrade the vCenter servers one by one .(3dyas gap between in each vcenter server)

Regards,

Surya

I don't see why not.. you will also have to upgrade IS at each VC.

Hi,

Do you have your SSO server in HA mode? I guess with 5 vCenters and a single SSO server you are risking the environment if the SSO are not in a HA or multiside mode. Well, for the upgrade, begin with SSO, then touch each vCenter which involves upgrade of inventory service as well.

Cheers

I haven't found any problems using 5.1.0b VC with the 5.1U1 SSO but if that's the recommendation we have to follow it
