About this task

Before migrating your vCenter Server deployment to an appliance, you can run a pre-check to find out the disk space requirement, the estimated upgrade time, and the extensions registered with vCenter Server Appliance. Running pre-upgrade is an optional but highly recommended step when planning your upgrade.

Procedure

  1. Run CLI Migrate using the --pre-check-only option.

    You can adjust your migration plans using the disk space requirements and estimated migration time. If you receive an error, you can troubleshoot and resolve the problem before the actual migration.

  2. Verify your template without deploying the appliance by entering the command: vcsa-deploy migrate --verify-only path_to_json_file.
  3. After resolving any errors, run the CLI Migrate command using the --verify-only option again until all errors are resolved.

Results

You are now prepared for an error-free CLI migration process.

What to do next

Perform a CLI Migration of vCenter Server from Windows to an Appliance.
