Premiere Pro Auto-Save location and interval: keeping recovery files usable across project format migrations

Question

GoalI want to configure Premiere Pro's Auto-Save so that recovery files remain usable even when a project undergoes a format migration (for example, opening an older .prproj in a newer Premiere Pro version that upgrades the project schema). The specific concern is whether the autosave file written after the migration can still be used to recover work if the migrated project is later closed without saving or becomes corrupted.Current understanding and constraintsAs I understand it, Auto-Save writes a temporary .prproj autosave file at a configurable interval (1–99 minutes, default 5) via Preferences > Auto Save, and the location can be changed from the project folder to a custom path. The autosave captures project state at the moment of the save, not unsaved edits beyond the last manual save point.What is unclear to me is the compatibility boundary: once a project is migrated to a newer schema, does the autosave file inherit the new schema (making it unreadable by the older version), and does pointing Auto-Save at a custom location change anything about naming, rotation count, or cleanup behavior?QuestionsAfter a schema migration, is the autosave file written in the new format only, or is any backward-compatible copy retained?Does a custom Auto-Save location affect how many autosave generations are kept or how they are named?Is there a documented way to verify which schema version a given autosave file contains before relying on it for recovery?

When you open an older .prproj file in a newer version of Premiere Pro and save it, the software performs a project schema migration. This process has significant implications for how Auto-Save files function.

Schema Compatibility After Migration
p>Once a project is migrated to a newer schema, any subsequent Auto-Save files generated by Premiere Pro will inherit that new schema. Premiere Pro does not retain a backward-compatible copy (the older version) of the project after the migration is saved. If you migrate a project and it later becomes corrupted, the most recent Auto-Save recovery file will be in the new format, making it unreadable by older versions of Premiere Pro.

Custom Auto-Save Locations
Pointing your Auto-Save location to a custom path via Preferences > Auto Save does not change the fundamental logic of the system. The following behaviors remain consistent:

Rotation Count: The 'Maximum Auto-Save Files' limit is strictly enforced regardless of whether the path is the project folder or a custom directory.
  Naming Convention: Files will follow the standard [Project Name] Auto-Save [Date and Time] format.
  Cleanup: Premiere Pro will delete the oldest files in the custom folder once the rotation limit is reached during a new save cycle.

Verification and Best Practices
There is no documented internal tool within Premiere Pro to inspect the schema version of a .prproj file without attempting to open it. To ensure recovery safety during a migration, consider:

Creating a manual backup of the original project before opening it in a newer version.
  If you must migrate, temporarily change the Auto-Save location to a separate folder to prevent the new schema from overwriting your existing legacy recovery files.
  Verify that your Auto-Save interval is set to a frequent duration, as the first auto-save after a migration will effectively overwrite your older-compatible recovery points.

Are you experiencing specific corruption errors after migration, or are you planning a workflow for a large-scale version upgrade?
