Currently, when attempting "Update product links" (https://support.atlassian.com/migration/docs/update-product-links/) and using override Migrating from staging instance,, there is not an option to input a mappings.csv file, which include an entire list of server pages, which are active.

This functionality will be helpful in phased migrations and when migrating from staging servers, and to fix any links on pages that were migrated earlier.

Scenario:

• Perform a phase1 migration of few spaces.
• Perform phase 2 migration of few more spaces.
  • This migration was from a staging server which was cloned from the Primary Server, and all the non-migrating spaces were deleted in this instance, for better performance
  • Perform link fixing and check for for any broken links on existing pages( as the pages were not migrated during phase1)

Workaround:

If any links are still noticed broken, reach out to support, to perform legacy link fixing for any supported links.
