vCenter 5.5 Upgrade with Windows Server 2012 R2 – Part 2 – OS Build

This is part 2 of the vCenter 5.1 to 5.5 Update 1c upgrade, detailing the Windows Server 2012 R2 OS installation and configuration.

This is an eleven part series, describing how to upgrade from vCenter 5.1 to vCenter 5.5:

Prerequisites

  • You have a validated design for your new vCenter management layer.
  • You have checked all systems that integrate with vCenter support vSphere 5.5 Update 1c.
  • You have an approved scheduled downtime from your Release Management team.
  • You have downloaded the necessary binaries.
  • You have a valid Windows Server 2012 R2 Data Center Edition licence (KMS server used in this case)
  • You have valid IP addresses and hostnames for the vCenter 5.5 servers.
  • You have administrator access (direct/indirect) to Active Directory, DNS, ESXi hosts, etc.
  • You have tested this process in a test environment before moving to Production.
  • You have an AD “vCenter” OU which has a “optimised” Group Policy configured specifically for vCenter.
  • You have a “optimised” Anti-Virus policy specifically configured for vCenter.

Preparing the vSphere Management Cluster

  1. Create the DRS VM-Host rule that binds the vCenter Management Layer to a single Host in your Management Cluster.
  2. Take vSphere Snapshots of your vSphere 5.1 Management Layer Virtual Machines as part of your roll-back strategy.  Make sure you include all VMs in the management ecosystem that integrate with vCenter: VUM, vCOPs, vCAC, vCD, CBM, vCM, vShield Manager, etc.
  3. Take a Database consistent backup of the vCenter 5.1 SQL Server database.
  4. Upload the ISO images (Windows Server 2012 R2, Microsoft SQL Server 2008 R2 & VMware vCenter 5.5 Update 1c) to a Datastore that your Host has access to.
  5. Connect your vSphere Client directly to the ESXi Host you selected in Step 1.
  6. Create the VM that will run Windows Server 2012 R2.  For a “Small” vCenter deployment, configure 6 vCPUs, 14GB RAM, 2 vDisks (100GB & 40GB), vNIC vmxnet3 and connect the CD-ROM to the Windows Server 2012 R2 ISO image.

Shutdown the Original vCenter 5.1 Servers

  1. Open the Console to your Web Client, Inventory and Web Client servers and gracefully shutdown the VMs.
  2. Open the Console to your vCenter/Database server and uninstall the vCenter 5.1 software.
  3. WARNING: DO NOT DELETE  “C:\ProgramData\VMware\VMware VirtualCenter\SSL\” DIRECTORY.  These certificates will be copied to the new vCenter server later on.
  4. Change the IP Address of the VM to another IP in the same subnet.  The original IP will be assigned to the Win2012 R2 server, which means you may not have to change a lot of firewall rules.
  5. Change the name of the VM to the organisational naming standard for databases.  The original name will be assigned to the Win2012 R2 server, this means administrators will continue to use the same name for access.  You will have to remove the VM from the Domain, change the name and add it to AD again.
  6. After the necessary reboots, login to the Database server and run the “SQL Server Management Studio”.  Login as “sa” with the relevant password.
  7. Browse to the “Database” folder and record the name of the vCenter Database configured, this will be required later.  Verify that “vpxuser” exists in the “Permissions” option under Database “Properties”.

  9. In the “Settings Window”, set the “Administrator Password”.
  10. When the “Press Ctrl+Alt+Delete to sign-in” message appears you can login.

  3. Set the Time-Zone.
  4. Disable the Windows Firewall for the Domain, Private and Public profiles.
  5. Configure the vNIC: IP Address of original vCenter 5.1 server, Netmask, Gateway and DNS servers.
  6. Disable Internet Explorer Enhanced Security.
  7. Change the computer name to that of the original vCenter 5.1 server and add to Active Directory.
  8. Move the Computer object to the “vCenter” OU in AD (Domain Admin task).
  9. Install Anti-Virus and set the “vCenter” AV policy (Information Security task).
  10. Check that the server licence is activated from the KMS server.
  11. Check that the server has been updated with the latest patches from the WSUS server.
  12. From “Server Manager”, select “Tools” and then “Computer Management”.
  13. Within the “Computer Management” window, select the “Disk Management” object.  Browse to the “Unknown” 40GB Disk and place it “Online”, then “Initialise” with “GPT” and finally create a “Simple Volume” that will map to E:.
  14. Within the “Computer Management” window, select the “Local Users & Groups” object.  Browse to the “Administrator” Group and add the administrator groups and users that will manage this vCenter.  In particular, your service account for vCenter must be added.

  1. We will migrate everything from VC 5.5 U2 (running over win2k8r2) to VC 6.0 (would run over w2k12r2). The inventory snapshot fling is not supported for the same. What is the best way to migrate permissions, alarms, all datacenter objects including all rules set under cluster, inherited permissions etc. over to the new built vsphere VC 6.0 running on 2012r2 VM?

    Any help will be highly appreciated.

  2. Thanks a lot for your documentation , I am currently in a similar situation . I also have to relocate Vcenter 5.1 to a new Vcenter 5.5 server. I am bit confused based on your explanations about the database . You have mentionned a database backup but I don’t see the steps for a database restore in your tutorials. I only see the 64 bits DSN steps. You are also backing up and restoring the Vcenter MSSQL database, am I right ? .

    • Thank you for reading. This series assumes that the database server remains intact and separate during the vCenter Server upgrade/re-install.
