Unable to migrate Calendar web part with Summary view (4322396)

When using a database (DB) connection on SharePoint 2010 to migrate a Calendar web part with Summary view to SharePoint 2013 that is using the Object Model (OM) connection, the error message below is seen in the log:

The issue is caused by a SharePoint 2010 bug.

As a workaround, do the following:

1. Navigate to the source site with the affected Calendar web part.
2. On the upper right corner of the web part, click the drop-down arrow and select "Edit Web Part".
3. On the List Views section, change the view on the Selected View dropdown.
4. Click OK, then re-run the migration job.
