Status

Historic data

Goals and plans

Phase 1: By the end of 2025, all historic 2025-data will be migrated to Dialogporten. 25/11: We will migrate data back to and including December 2024 as part of this.

Phase 2: Older data will be migrated by Q2 2026, starting with the newest data first.

Details

Dialogs in Dialogporten come from three sources: directly via Dialogporten’s API, from Correspondence (messages), or app instances (e.g. filled forms). For the two latter, we separate between data created in Altinn 2 and data created in Altinn 3, and between live-sync of changes and migration of historic data.

For each of the different data sources below, a brief status update, explanation of the source and any other relevant details.

✔ Dialog services

All changes done directly to Dialogporten’s API is available immediately.

Typically used where the service owner either has their own platform, or handle dialogs outside the default functionality of Altinn Correspondence or Altinn Studio/apps.

⚠ A2 Correspondence - Historic

Currently migrated back to 1st of December 2024. Older correspondence will be migrated later.

Manual process. Historic correspondence is migrated from Altinn 2 correspondence to Altinn 3 correspondence. The correspondences are then migrated to Dialogporten in a separate process.

See correspondence data-migration for details on the migration process.

✔ A2 Correspondence - Live

New messages created in Altinn 2 correspondence are migrated to Dialogporten in near real-time (every 5 minutes). Live sync is active for both tt02 and prod. See correspondence data-migration for details on the synchronization process.

✔ A3 Correspondence

All new messages created in Altinn 3 correspondence are available in Dialogporten immediately. No migration needed.

⚠ A3 App instances - Historic

Migrated back to 1st of January 2025. Older app instances will be migrated later.

✔ A3 App instances - Live

New app instances created in Altinn 3 are available in Dialogporten immediately. Changes are synced in real-time.
