Monitor a Migration Job
On this page
You can monitor a migration job from the History pane on the Data Migration tab. The History pane contains information about in progress, completed, and failed migration jobs.
About this Task
Migration jobs execute in a number of distinct stages, which are visible on the Job overview pane.
For example:
A snapshot migration job includes a snapshot stage and, optionally, a verification stage.
A continuous migration job includes a snapshot stage, followed by a CDC stage.
