You can monitor the status of a Droplet migration within the DigitalOcean Control Panel.
To see the status of a migration, select the Droplet within the control panel. A banner appears at the top of the page showing if the migration is still in progress. If the migration is no longer in progress, the banner does not appear.
You can also check if a migration has completed by viewing the Droplet’s history. To view a Droplet’s history from the control panel, click on the Droplet being migrated from your list of Droplets, then click History in the side navigation menu. This shows when the migration began and how long it took to complete.
