5. Re-create the resource pool:

   1. On the source vSRX cluster, right-click its resource pool and click Edit resource Settings. Write down the reservation values for CPU and memory.
   2. On the target vSRX cluster, right-click New Resource Pool and create a resource pool with the same name as the source vSRX resource pool. Set the reservation values for CPU and memory to the same values as the source.

6. Migrate the vSRX edge nodes VMs:

   1. Right-click the <vm_nickname>_vSRX_edge_node1 VM and click Actions > Migrate.
   2. Under Select a migration type, choose Change both compute resource and storage.
   3. Under Select a compute resource, choose the target cluster of the vSRX resource pool and click Next.

   5. Under Select networks, choose the destination network by browsing to the appropriate DVS switch and click Next.
   6. Under Select vMotion priority, choose a priority option.
   7. Under Ready to complete, verify the information and click Finish to start the migration.
   8. Repeat the previous 7 steps for the <vm_nickname>_vSRX_edge_node2 VM.

7. Create VM groups on the target cluster:

   1. Click the target cluster.
   2. On the Configure tab, under Configuration, click VM/Host Groups.
   3. Under VM/Host Groups, click ADD.
   4. Under Add Group Member, select the type as VM Group and click ADD.

   2. On the Configure tab, under Configuration, click VM/Host Rules.
   3. Under VM/Host Rules, click ADD.
   4. Under Create VM/Host Rule, select the type as Virtual Machines to Hosts and map <vm_nickname>_vSRX_edge_node1 to the host where it is deployed. Assign the same name <vm_nickname>_vSRX_edge_node1.
   5. Complete the previous step for the <vm_nickname>_vSRX_edge_node2 node.

9. Enable the affinity rule on the target cluster:

   1. Click the target cluster.
   2. On the Configure tab, under Configuration, click VM/Host Rules.
   3. Search for and locate <vm_nickname>-affinity-rule.
   4. Click Edit and select Enable Rule.

If you are migrating from a source vSAN OSA (Original Storage Architecture) to a target vSAN ESA (Express Storage Architecture) cluster, also configure the failover settings:

1. Click the target cluster.
2. Click the Networks tab, select the vsrxnickname-vsrx-fab DVS switch, and click the Configure tab.
3. Under Policies, click Edit and go to Teaming and failover.

5. Repeat the previous 3 steps for the vsrxnickname-vsrx-private-transit and vsrxnickname-vsrx-public-transit DVS switches.

Procedure to create corresponding port groups (RiskForesight)

If the Caveonix RiskForesight service is installed on your instance, complete the following procedure.

RiskForesight is installed with its own port group named SDDC-DPortGroup-Caveonix. Before you migrate the management VMs for instances with this service deployed, you must create a corresponding port group in the new (target) cluster.

1. In the vSphere Web Client, click the Networks tab, right-click SDDC-DPortGroup-Caveonix, and click Export Configuration.
2. Under Export Configuration, click OK.
3. Right-click the private network subnet of the target cluster and click Distributed Port Group > Import Distributed Port Group.
4. Under Import port group configuration, click Browse and upload the exported configuration archive file that you created in Step 2. Click Next.
5. Under Ready to complete, verify the information and click Finish. Confirm that the subnet is to be renamed.
6. Complete the procedure to migrate management VMs.

Procedure to migrate management VMs

1. In the vSphere Web Client, go to the Virtual Machines tab, select the VM that you want to migrate and click Actions > Migrate.

2. Under Select a migration type, choose Change both compute resource and storage.

3. Under Select a compute resource, choose a target cluster or host in the target cluster.

   If VMware HCX is installed on your instance, you might get a compatibility error, which you can ignore. For more information, see vCenter vMotion error "Virtual Ethernet Card 'Network Adapter 1' is not supported".

4. Under Select storage, choose the vSAN datastore name for the target cluster.

   If the target cluster has a higher version for the virtual switch than of the current cluster, you receive an error. For more information, see Migrating a virtual machine between two different vDS versions.

5. Under Select networks, ensure that the dpg source networks are equivalent to their target cluster. Do not change the edge-teps, as added clusters cannot create their own networks. Also, the destination network that is marked as none is a known issue and can be ignored.

6. Under Select vMotion priority, choose a priority option.

7. Under Ready to complete, verify the information and click Finish to start the migration.

Procedure to deploy the NSX edge management VMs on the new cluster

After you migrate the management VMs, you must deploy the NSX edge management VMs on the new (target) cluster.

Review the following information before you redeploy:

• Ensure that a new subnet is available on the same VLAN as the IP addresses assigned to the original (source) NSX edge.
• Obtain the DNS and NTP server details from IBM Support.

Complete the following steps in NSX Manager:

1. Click the System tab and from the left navigation menu, click Fabric > Nodes > Edge Transport Nodes and click Add Edge Node.

2. Under Name and Description, enter a name for the new (target) edge, the hostname in FQDN format, and select the Medium option for Form Factor. Click NEXT.

3. Under Credentials, enter the passwords for both the admin and root users and toggle the Allow SSH Login and Allow Root SSH Login switches for debugging purposes. You can skip the Audit Credentials section. Click NEXT.

4. Under Configure Deployment, select the Compute Manager, Cluster, and Datastore values from the list. Cluster and Datastore refer to the new (target) cluster. Click NEXT.

5. Under Configure Node Settings, select IPv4 Only for Management IP Assignment and Static for Type. Enter the Management IP and Default Gateway values and click Select Interface.

6. Under Select Interface, choose the portgroup with the name that ends with dpg-mgmt and click SAVE.

7. Under Configure Node Settings, enter the DNS and NTP server details, previously obtained from IBM Support. Click NEXT.

8. Under Configure NSX, add the following NVDS (NSX Virtual Distributed Switch) switches with the indicated settings:

   1. For the edge-teps switch:

      • Transport Zone - tz-vm-overlay
      • Uplink Profile - edge-tep-profile
      • IP Address Type (TEP) - IPv4
      • IPv4 Assignment (TEP) - Use IP Pool
      • IPv4 Pool - Choose the pool with the name that matches the cluster to which you are deploying the new edge nodes.
      • Click Select Interface and choose VLAN Segment for Type, then select edge-teps and click SAVE.

   2. For the edge-private switch:

      • Transport Zone - edge-private
      • Uplink Profile - edge-private-profile
      • Click Select Interface for uplink2 and choose Virtual Switch/Distributed Virtual Portgroup for Type, then select dpg-edge-uplink and click SAVE.

   3. For the edge-public switch:

      • Transport Zone - edge-public
      • Uplink Profile - edge-public-profile
      • Click Select Interface for uplink2 and choose Virtual Switch/Distributed Virtual Portgroup for Type, then select dpg-external and click SAVE.

9. To complete the configuration and start the deployment of the edge node, click FINISH.

10. Repeat the previous steps to create an additional NSX edge node for replacing the original (source) node. By default, your configuration has a services edge and a customer edge, but it might include other edges that you deployed.

11. After all new edge nodes are deployed, replace the old nodes with new nodes. For each node pair:

    1. Click the System tab and from the left navigation menu, click Fabric > Nodes > Edge Clusters.
    2. Under Actions, click Replace Edge Cluster Member.
    3. Under Replace, select the old edge node and under With, select the newly deployed edge node.
    4. Click Save.

12. Verify that the newly added nodes are correctly configured:

    1. Go to Networking > Tier-0 Gateways or Networking > Tier-1 Gateways and to the cluster name where the new nodes were added.
    2. Click the active/standby configuration to confirm that the newly added nodes are listed in both the Active and Standby states.

13. After you confirm that all new nodes are working correctly, delete the original (source) nodes:

    1. Click the System tab and from the left navigation menu, click Fabric > Nodes > Edge Transport Nodes.
    2. Select each of the original nodes and delete them one by one. This step also deletes the old nodes from the vCenter Server cluster.
