Release 2 Data Migration

This phase migrates existing data to work with the new reconciliation and group-based permission model. No user action is required.

What Changed

Behind the scenes, SyRF classifies every existing study based on its annotation history:

  • Studies annotated by a single person are automatically promoted -- their answers become the gold standard with no manual intervention. This means existing single-annotator projects benefit from reconciliation retroactively.
  • Studies annotated by two or more people enter the reconciliation pool, ready for reconcilers to review using the new Reconciliation Workflow.

Existing project administrator permissions are mapped to the new group-based permission model. The built-in Administrators group receives full permissions on every stage, preserving current access. You do not need to reconfigure any permissions.

Controlled Rollout

Reconciliation features are enabled in a controlled order behind feature flags:

  1. Group-based permissions (foundational -- runs first)
  2. Reconciliation model (auto-promotion happens in the background)
  3. Reconciliation workflow (the UI becomes available to reconcilers)

This phased approach ensures each component is stable before the next is activated. All changes are additive -- no existing data is deleted or modified destructively. If anything goes wrong, the changes can be safely reversed.
