We are looking at copying data from one of our HubSpot portals to another. We exported our contact information into the new portal, but the contactIds are distinct from portal to portal. We looked into the get engagement and post engagement apis, but the contact and deal Ids do not match from portal to portal. This caused the posted engagements to say “HubSpot user” instead of the correct HubSpot users name. Does anyone have any advice or recommendations on how we can go about accomplishing this task?
