Re: vCenter upgrade from 5.1 to 5.5 and consolidation

I went through this KB before but it does not talk about scenario I have. I can use simple install or Custom method to install all three components but it will not detect earlier version of SSO on my vcenter server as it is installed on another VM, let me re-iterate :-

My existing VSphere 5.1 setup has SSO installed on SSOVM01, Inventory service on INVENVM01 & vCenter installed on VCVM01. I want to have all three upgraded to 5.5 U1 & installed on VCVM01. So tradition way of simple install or custom would simply install SSO & inventory service on VCVM01, they would not find any previous version.

However vCenter's earlier version would be detected as I am running the setup on VCVM01 itself. So to get all of them upgraded, this is the plan : -

I think this should work...but have not tested it myself.

1. Install SSO 5.1 on the current vCenter server (which I assume is still on 5.1)
2. Back up your existing SSO DB - kb.vmware.com/kb/2034928
3. Restore the backed up SSO DB to your new instance
4. Associate vCenter with the new SSO instance  - kb.vmware.com/kb/2033620
5. Then go forward with your upgrade

Please suggest if you think otherwise.

Thanks,
