Renew certificates in System Center 2012 R2 Virtual Machine Manager RRS feed

  • Question

  • Guys,

    how do I renew certificate in System Center 2012 R2 Virtual machine manager HA with UR12.

    SCVMM 2012 R2 UR12 - 3.2.8377.0

    Got one article which suggest how to do it but the cert renewal tool is for UR14. - https://support.microsoft.com/en-in/help/4086006/renew-certificates-in-system-center-2012-r2-virtual-machine-manager

    Any one knows how to renew within UR12 for HA VMM node?

  • Hello,

    To my knowledge, the best way is to install the UR 14 for the VMM server.

    Then, you can follow the procedures in the KB article to renew the certificates.

  • thanks mate

    we have UR13, do you think its worth to try and use the procedure on current UR without upgrading the to UR14 or it will just fail?

  • or if there is any other way to do it?

    such as this - https://adfordummiez.com/?p=499 - I know it applies for standalone VMM but there might be a way to do it for HA VMM too?

  • Hi,

    I would recommend upgrading to the latest Update Rollup 14, and then attempt to renew the certificates, whether it's needed or not for renewing the certificates, it is still important to keep the software up-to-date to the latest if possible.

    For renewing the certificates of the VMM servers themselves, as you've already found follow the procedure here: Renew certificates in System Center 2012 R2 Virtual Machine Manager

    For renewing certificates on managed hosts within VMM, you simply run the following script:

    $Credential = Get-Credential
    
    Get-SCVMMManagedComputer -ComputerName "SCVMM2012.contoso.com" | Register-SCVMMManagedComputer -Credential $Credential
    (Run this from the SCVMM server).


    Best regards,
    Leon

  • Well I know it’s always recommend to have up to date updates but my environment involves windows azure pack with Dmz nvgre gateway cluster which doesn’t support straight vmm agent update hence I am not looking to break it just for certificate renewal so is it possible to use Same instruction for ur13? Please advise

  • If the KB article states that you need Update Rollup 14 to run the tool, then that’s your answer, this is the supported way to do this.

    While it ”may” work with running an earlier update rollup, it will probably not be supported method, this means that if you encounter any issues, you might not get support from Microsoft.

  • thanks mate, as Its just a certificate renewal and nothing that we are actually installing, so if we run into issues after doing so, can we revert back using VMM DB backup / restore or VMM snapshot revert?

  • Yes you should be able to do a snapshot revert or DB restore if something goes wrong.
