Transition solution

Transition solution for Altinn Correspondence

This section of the documentation is a work in progress. There are sections with missing or only partial documentation. Some functionality is still under analysis and development, and does not represent the final production version.

To simplify the transition from Altinn 2 to the Altinn 3 version of the Correspondence product, an overall strategy has been followed aiming to balance complexity and user-friendliness for all parties.

  • Altinn 3 Correspondence largely has the same data model as Altinn 2 to enable mapping/migration.
  • All Altinn 2 Correspondences and attachments are migrated into Altinn 3 Correspondence.
  • All Altinn 2 Correspondence services with data will be created as Altinn 3 Correspondence services.
  • Data/metadata is migrated in a process that also makes the elements available in the Dialogporten and Arbeidsflate.
  • Migration of historical data will take time (weeks/months), and the transition solution is built with this in mind.
  • Eventually, the migration job will “catch up” with live/fresh data, so the elements can be made available in Altinn 3 shortly after they were created in Altinn 2.
  • To become independent of the production date for the new Arbeidsflate, Altinn 3 Correspondences are made available in the Altinn 2 Portal for end users.
  • No transition solution is made for API endpoints:
    • End-user systems and Service Owner systems must maintain integration with both Altinn 2 and Altinn 3 during a transition period.
