Migrate Vxrail cluster version 7.0.401 from Vcenter7 to Vcenter 8

Hello userdell97e0d6,

You are correct that there is not a document that explains how to do this. Here are some basic steps that you can do to ensure that your migration goes smoothly.

1.       Prepare for Migration:

·  Ensure that the target vCenter has a build number equal to or greater than the source vCenter.

·  Schedule the migration during a maintenance window to minimize impact on running VMs.

2.       Enable vLCM on Target vCenter:

·  Log in to the target vCenter vSphere UI with an administrator account.

·  Navigate to the target cluster, click the "UPDATE" tab.

·  Click "Image" and then "SETUP IMAGE".

·  Select any base image from the dropdown list and click "SAVE".

·  Click "FINISH IMAGE SETUP" to enable vLCM on the vCenter level.

3.       Disable vLCM on VxRail Level (if necessary):

·  SSH into VxRail Manager and run the following command as the root user:

curl -i -X PUT --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock http://localhost/rest/vxm/internal/configservice/v1/configuration/keys/vlcm_enabled -H "Content-Type: application/json" -d '{ "value" : "false" }'

4.       Run the Migration Tool:

·  Use the VxRail vCenter Migration Tool, which operates using a Python script named vc-migrate.py.

·  Ensure both vCenters can be accessed and that the migration tool is run on VxRail Manager.

5.       Post-Migration Steps:

·  After migration, manually reassign the vSphere and vSAN licenses on the target vCenter (note that 8.x cannot reuse 7.x vSAN licenses).

·  Reconfigure any VxRail components that do not migrate automatically.

6.       Monitor Migration Progress:

·  The migration tool provides clear prompts and tracks progress through workflow_progress.json.

By following these steps, you can successfully migrate your VxRail cluster to vCenter 8.
