mozharness gecko migration merge day script
We may require separate aurora + beta steps at some point.
Assignee: nobody → aki
This review can definitely wait til you're not on pto. This is a single script and 4 config files. gecko_migration.py can handle all 4 types of migrations: beta_to_release, aurora_to_beta, central_to_aurora, and staging_beta_migration. This is handled by "migration_behavior" which specifies which workflow to use after tagging and merging. This also fixes a couple other bugs: the debugsetparents method tries to preserve old tags, and we now touch the CLOBBER file per bug 1003634. This handles the release migration in bug 1011794, but not the release l10n migration.
