Migrating to an existing vCenter

After deploying NetApp HCI, you can migrate your installation from the vCenter instance deployed with NetApp HCI to an existing vCenter instance in your environment.

Before you begin

If you chose to install vCenter 6.5u2 during NetApp HCI deployment:
  • Your existing ESXi environment is version 6.5u1 build 5969303 or later.
  • Your existing vSphere environment is version 6.5u2 build 8307201 or later.
If you chose to install vCenter 6.0u3 during NetApp HCI deployment:
  • Your existing ESXi environment is version 6.0u3 build 5050593 or later.
  • Your existing vSphere environment is version 6.0u3a build 5202527 or later.

Steps

  1. Browse to the IP address of the newly installed vCenter instance you installed during NetApp HCI deployment. For example:
    https://<IP address>/vsphere-client
  2. Log in to the new vCenter instance.
  3. Export the vSphere Distributed Switch (VDS) configuration:
    1. Go to Home > Networking.
    2. Right-click NetApp HCI VDS and select Settings > Export Configuration.
    3. In the resulting dialog box, select the Distributed switch and all port groups option.
    4. Click OK.
    5. Click Yes.
    6. Save the backup file to your computer.
  4. Unregister the NetApp Element Plug-in from the new vCenter:
    1. Browse to the IP address of the NetApp HCI management node. For example:
      https://<management node IP address>:9443
    2. Click Element Plug-in Registration.
    3. Select Registration Status.
    4. Provide information about the new vCenter and click Check Status.
    5. Click the Unregister Plug-in tab.
    6. Click Unregister.
  5. Disconnect all connected hosts from the new vCenter instance:
    1. Identify the ESXi host that is running the vCenter virtual machine (disconnect this host last).
    2. Right click on each of the other ESXi hosts and select Connection > Disconnect, ending with the host that is running the vCenter virtual machine.
  6. Browse to the IP address of the existing vCenter instance.
  7. Log in to the existing vCenter instance.
  8. Create a new cluster in the existing vCenter instance, using the following settings:
    • Name: Duplicate of the existing cluster name from the new vCenter instance
    • DRS: Turn ON
    • Automation Level: Fully automated (default setting)
    • Migration Threshold: 50/50 (default setting)
    • vSphere HA: Turn ON
      • Host Monitoring: Enabled
      • Admission Control: Disabled (unchecked)
      • VM Monitoring Status: VM Monitoring Only
      • Monitoring Sensitivity: High (default setting)
    • EVC:
      • Disabled (for deployments with compute nodes of the same generation)
      • Intel Broadwell Generation (for deployments with compute nodes of mixed generations)
    • Virtual SAN: Disabled (default setting)
  9. Add existing NetApp HCI hosts to the existing vCenter cluster you created:
    1. Right-click on the newly created cluster and select Add Host.
    2. Provide the IP address and credentials of the new ESXi host, and follow the prompts that appear.
    3. Click Next.
    4. Click Finish.
    5. Repeat these steps for any ESXi hosts that you disconnected from the new vCenter instance.
  10. Register the NetApp Element Plug-in to the existing vCenter instance.
    1. Browse to the IP address of the management node. For example:
      https://<management node IP address>:9443
    2. Click Element Plug-in Registration.
    3. Click Register Plug-in.
    4. Provide the IP address and credentials of the existing vCenter instance.
    5. Click Register.
  11. Power off the new vCenter instance.
  12. Log out from the existing vCenter instance.
  13. Log back in to the existing vCenter instance.
  14. Add the NetApp HCI storage cluster in the NetApp Element Plug-in:
    1. Select NetApp Element Plug-in > Clusters > Add Cluster.
    2. Provide the management IP address, hostname, and credentials of the cluster.
    3. Click OK.
  15. Add the management node settings to the configuration:
    1. Select Home > NetApp Element Configuration > mNode Settings.
    2. Click the Action menu and select Configure.
    3. Provide the IP address, hostname, and credentials of the management node.
    4. Ensure that the management node status is UP.
  16. Use the NetApp HCI API interface to reconfigure alert integration settings for NetApp HCI:
    1. Browse to the API URL of your NetApp HCI system. For example:
      https://<IP address>:8443/swagger-ui.html
    2. Run the following API command using the IP address of the new vCenter instance:
      vcenter:vcenter > DELETE /vcenter
  17. Import the saved vSphere Distributed Switch (VDS) configuration into the existing vCenter:
    1. Log in to the existing vCenter instance.
    2. Go to Home > Networking.
    3. Check for an existing VDS with the name of NetApp HCI VDS and delete it if it exists.
    4. Right-click on the NetApp-HCI-Datacenter object and select Distributed Switch > Import Distributed Switch.
    5. Browse to and select to the file that you saved earlier.
    6. Enable the Preserve original distributed switch and port group identifiers option.
    7. Click Next.
    8. Click Finish.
  18. Connect to the NetApp HCI management node and do the following:
    1. Remove the new vCenter entry from the /sf/hci/nma/conf/nma.conf file.
    2. Restart SIOC by running the following command:
      sudo service sioc restart
