Accessing the Migration Report
Going to youravaloninstance.com/admin/migration_report/ will take you to the Migration Report showing similar information on your migration progress.
The live update button on the bottom tells the page to refresh the report every five seconds.
You'll notice as you first start importing that all of your media objects will jump to either "Failed" or "Waiting". Media objects in "Waiting" are waiting for the "second pass" which will connect them with their masterfiles and derivatives. During the second pass these object will move to either "Failed" or "Completed".
You can drill down to a class type and see items and some basic migration info. This is a good place to check for migration errors to work on.
Clicking on an item brings up a detailed view of any datastreams that are attached to the item.
You can look at the datastreams (including any images) below the header under Fedora 3 or Fedora 4. Viewing the datastreams from Fedora 3 is a live query that requires the Fedora 3 instance to be running and responding to requests. Once the Fedora 3 instance from your previous Avalon installation is stopped, this information will no longer be available from the Migration Report.
Not everything created in Fedora 4 for a migrated MediaObject will show in this report, such as access control and list_source objects (ordering via proxies).
Some migrated items won't have fedora datastreams attached to them. There are some items that are migrated straight from the database. For now they have limited details pages. After you run the avalon:migrate:db rake task, the db items will also show up in your migration report.
