Updating to newer build of vCenter 5.5

[Fluxblocker]

Greetings to all.  I hope this will be a simple question since I am a simpleton.  At least I feel like one, because I am trying to update a Windows vCenter server from version 5.5.0 Build 2001466 to the latest build which is 5.5 Update 2e which I think is build  2646482.  When I try to run the installer, I get a message saying something to the effect that the program is already installed.  Is it mandatory that I uninstall and remove everything and then install the newer build?  There has got to be an easier way... do I need to update one component at a time?  I have used the update manager many times to update the ESXi hosts; I run the scan, then stage, then remediate - that usually works fine for updating components on the hosts and VMs, but I can't seem to use this method to update vCenter, and when I try the installer, well, it is like I said above.  I hope there is an easy way to update it without completely uninstalling it and doing a bunch of fancy database manipulation.  But if that is what it takes, then so be it.  I can't seem to find a good technical document either - they are all about upgrading from 5.1 to 5.5 or something to that effect.  So I will certainly be very grateful, most sincerely, for any help or suggestions anyone might have.

Many thanks,

Sam of Son

You're using the Windows version of vCenter ? You're trying running the installer using the Simple install or Custom install ? Try using the Custom install and upgrade each component at time in the following order:

1. Upgrade vCenter Single Sign-On;

2. Upgrade vSphere Web Client;

3. Upgrade vCenter Inventory Service;

4. Upgrade vCenter Server.

That makes perfect sense!  I should have thought of that but I am becoming a simpleton lately, trying to do too many things at once!

I will try it and come back and mark it correct - I am confident it will work.

Thanks!

Just a final tip, make sure take a backup (and/or snapshot) before start the update.
