After you upgrade to vCenter Server, consider the post-upgrade options and requirements.
- Complete any component reconfigurations that might be required for changes during upgrade.
- Verify that you understand the authentication process and identify your identity sources.
- If you migrated vCenter Server on Windows to a target vCenter Server appliance and you use any local OS user names to log in to the vCenter Single Sign-On, you must recreate them and reassign permissions.
- If you performed an upgrade, upgrade any additional modules that are linked to this instance of vCenter Server, such as Update Manager. If you performed a migration from vCenter Server for Windows to a vCenter Server appliance, the Update Manager module is migrated as well into vSphere Lifecycle Manager.
- Optionally, upgrade or migrate the ESXi hosts in the vCenter Server inventory to the same version as the vCenter Server instance.
- If you use Update Manager in your vCenter Server deployment, and Update Manager and vCenter Server were running on separate machines prior the migration, consider to shut down or delete the Update Manager host machine after the migration is complete. Before disposing of the Update Manager host machine, take into account the following:
- You might need the host machine for rolling back purposes of your upgraded or migrated environment.
- You might have other software that runs on that machine.
