+Only users who have deployed a FastGPT version earlier than `<4.8` need to run this step.
 
 Starting from V4.15.0-beta7, workflow save payloads use the V2 structure consistently. Historical `apps.modules` and `app_versions.nodes` records may still use the V1 structure. Run the V1 -> V2 migration first, then run the V2 dirty-data cleanup in the next step.
