// From 2013-2016, this migration moved revisions attached to tasks to edges.
Move Task <=> Revision storage to Edges Summary: - Add edges for this relationship. - Use edges to store this data. - Migrate old data. - Fix some warnings with generating feed stories about Aux and Edge transactions. - Fix a task-task edge issue with "Create Subtask". Test Plan: - Migrated data, verified reivsions showed up. - Attached and detached tasks to revisions and vice versa. - Created a new revision with attached tasks. - Created a subtask.

Remove three ancient columns from Maniphest tasks: attached, projectPHIDs, ccPHIDs Summary: Before edges, we stored some of this stuff directly on tasks. - `attached` was migrated to edges in Jan 2013. - `projectPHIDs` was never used, as far as I can tell? - `ccPHIDs` was migrated away and dropped more than a year ago. None of these columns are used in modern code (instead, modern code uses edges). Test Plan: `grep`, browsed around, `bin/storage upgrade`, unit tests.
