Is it Possible to Programmatically Override Activity Story LastUpdate Date on Creation?

Background: Migrating approximately 64,000 posts using REST API to create threads/replies.

Issue: Date for posts entered appropriately. Activity Story Stream uses the REST Migration date instead of the post date/time, pushing other, non-migrated content down 64K spaces.

Activity Story has correct "Created" date but LastUpdate shows the migration time (which I suppose is technically correct) not the merged date.

Is there a method to override this?

  • Digging deeper, it appears that the post Add date seems correct but the Replies are not referencing the date set from REST but the time it was imported:

    I'm not sure if that information is helpful, but wanted to share in case it is easier to change/update.
