Export to PDFAfter the domain name of your source tenant is changed to your destination tenant for go-live, if you want to perform a final incremental migration to migrate the new or modified data to the destination, you must change the host names of the source and destination object URLs configured in project mappings first.
Refer to the following steps to change the host names of the source and destination object URLs:
Click Projects in the left pane to access the Projects page, and click the name of a project.
On the Project mappings page, select one or multiple mappings for which you want to change host names.
Click Post-migration, and select Change mapping domain to change host names for the object URLs.
In the Change mapping domain panel, the original source host name and destination host name are automatically displayed.

Enter a new source host name and destination host name for the objectURLs, and click Change to change the host names.
After changing the host names, the original host names of the source and destination object URLs will be updated to the new host names.
