During the upgrade of a vCenter Server Appliance that uses an external Update Manager, the Migration Assistant must be running on the source Update Manager machine. This procedure describes how to download and run the Migration Assistant manually before the upgrade.
Alternatively, if you plan to upgrade the vCenter Server Appliance by using the CLI installer, you can add the source.vum section section and run.migration.assistant subsection to your JSON template. For information about the CLI upgrade configuration parameters, see Upgrade Configuration Parameters.
Prerequisites
- Download and Mount the vCenter Server Appliance Installer.
- Log in to the source Update Manager machine as an administrator.
Procedure
- From the vCenter Server Appliance installer package, copy the migration-assistant directory to the source Update Manager machine.
- From the migration-assistant directory, double-click VMware-Migration-Assistant.exe and the provide the vCenter Single Sign-On administrator password.
- Leave the Migration Assistant window open until the upgrade of the vCenter Server Appliance finishes.
Results
When the pre-checks are finished and any errors are addressed, your source Update Manager system is ready for the upgrade.
Caution: Closing the Migration Assistant window causes the upgrade process to stop.
