As Web UI expects SVG icons only for document types, a migration path has to be provided for existing projects.
- Release notes explain the migration path to follow
- It mentions explicitly that the migration does not provide a path backwards
- Migration can be triggered manually
- Migration can be relaunched in case of failure / interruption
- A fallback mechanism is provided in Web UI so that applications keep working in a degraded state even if the migration has not been triggered yet
