    How do I uninstall VCenter and SSO without losing VMs?

    Touchsuite Lurker

      Apparently, VMWare is very willing to help customers buy licenses for their evaluation software but if a customer decides they do not want the software VMWare will NOT help uninstall it unless the customer buys a service contract for the software they want to uninstall!

       

      A former admin (way back) at my company installed VCenter using an "evaluation license" and created several production VM servers on it.  The evaluation license has run out long ago and we cannot access VCenter.  I want to uninstall VCenter without losing the VMs.  Can anyone help me remove VCenter without removing the VMs?  Thanks.

          Hello,

           

          Vcenter can be completely decommission without impact on VM. (only in case of share storage DRS, HA etc...)

           

          Before remove Vcenter, But be sure that your ESXIs are right licensed

           

          You can proceed by shutdown your Vcenter :-) for see if everything works fine.

           

          Regards,

            The VMs are running on your ESXi Hosts and not "in" vCenter.   So verify if you have the login credentials of all of your ESXi hosts can can manage them trough the browser based "Hostclient" (https://youresx/).   If so you can disable HA, DRS and maybe other features the former Admin maybe have enabled within the Eval period by using vCenters WebClient.  After that you can simply shutdown the VCSA VM.  If there is a computer Object of your VCSA in your Windows AD you can remove it as well. Cleanup DNS and your done.

             

            What kind of license runs your ESXi hosts?

              Management workload and virtual machine workload in the vSphere environment are two different aspects, so you can easily remove the vCenter Server as the primary management component of virtual infrastructure without concern about VM interruption. Just as the other experts mentioned, check the following settings:

              1. Cluster configuration if you have, especially HA & DRS settings

              2. vSphere distributed switch if it's configured (VDS is ready to use if you provide the vSphere Enterprise Plus license for your ESXi hosts)

              And also, check the configuration of the Backup solution that you have. Is it connected to the vCenter or directly to the ESXi hosts?

                ..and in adittion to what has been mentioned above you will probably need a free license for the ESXi host in order to manager your VMs. It it's currently running with an expired license you will not be able to power on any VMs if they stop running.

                 

                You can find such a license here:
