(typos corrected below)
- To start, on your PS4, make sure you have your save file uploaded to the PlayStation cloud. If you aren't sure, go to Settings, then "Application Saved Data Management", then "Saved Data in System Storage", then "Upload to Online Storage", then "Borderlands 3". Choose your save then choose Upload.
All the remaining steps are on the PS5.
- On your PS5, go to Settings > "Saved Data and Game/App Settings"
- Delete all the Save files you have locally stored on the PS5 for both game versions: PS4 version and PS5 version.
