VCenter 5.0 to 5.1 U1 Upgrade while Separating or Splitting out Services (Part 4): Vcenter Service

We are now to the final piece to get the base 5.1 U1 upgrade completed.  In this first part, we need to uninstall the original inventory service and in order to do this we must uninstall the Vcenter service.  So, be sure to put in a change control or notify anyone that your Vcenter will be down during this time.   Important!  Your local accounts will not be imported into the permissions on your upgrade.  In order to use local non domain users they must be on your SSO server, but this is not the recommended method.

1. Log on to your Vcenter server.  Go to Control Panel and select Uninstall a program.


2.  Find the Vmware Vcenter Service and choose uninstall.


3.  Hit yes and uninstall the service, but don’t remove database if the option is given.


4.  Start Vcenter Installer and choose Vcenter installation or open Vcenter installer directly from its subfolder.

vc-15.  Enter your license key or choose to skip and enter it

6.  Choose use existing database and select your DSN.

vc-37.  Enter the database username and existing password


8.  The warning below will appear if you are using Vmware Update Manager which is most likely the case in most enterprises.  This just means you will not be able to use VUM until you upgrade that component. Which I recommend doing right after this upgrade.


9.  Choose to Upgrade your existing Vcenter Server Database.  Be sure to have a backup prior to continuing if you didn’t have one already!


10. Choose automatic to update the hosts with the new agent.  This should not cause any downtime, but be sure to have a Change Control in place if your enterprise requires it to cover your bases.


11.  Choose SYSTEM account or run the service under your standard.  Make sure the FQDN of your Vcenter server is correct.


12.  Take default ports or change to your needs.


13.  Set the JVM size based on your environment, but I always go larger if you feel you will grow into it over time.  This can be modified later if

13.  Enter your SSO FQDN and Username/Password that was created in part 1.


13.  You will see this warning if you have users that were local.  It will store them in the system temp folder which should be %temp%


14.  Enter your Inventory Service Server FQDN that was created in Part 3.


15.  Select the location to install Vcenter to.


16.  Wait for Vcenter install to

17.  Once complete, you are done and ready to test your login.  Load up the web client http://Vcentername:9443 and attempt to login.  If you have it correct, you should see your Vcenter listed.  If something with your SSO or login isn’t correct, you may not see your Vcenter.  Double check you have the right Domains added under the web client configuration.  You can still use the fat client if you need to get into Vcenter while you troubleshoot your Web Client/SSO.


Vcenter Installation is done!  Now you will want to go upgrade Vmware Update Manager.  It is basically the same process that we did here.  You run Vum installer and choose to upgrade your database.  The only caveat with VUM is that it only has scanning and compliance in the web client.  You must still use the VI client with 5.1 in order to create baselines and upgrade your hosts.  In future postings, I will show how to create a baseline in VUM, create your own iso, and update hosts.
