Well, in case you do want to try it out:

For models, assuming your original URLs start with s3://<old-bucket-name>/ , you'll need a JS script, something like:
db.model.find({uri:{$regex:/^s3/}}).forEach(function(e,i) { e.uri = e.uri.replace("s3://<old-bucket-name>/","s3://<new-bucket-name>/"); db.model.save(e); });
And than:
` sudo docker exec -it clearml-mongo /bin/bash

paste script into this file and exit nano

nano script.js

this should run the script against the backend db

mongo backend script.js `
Please take care : since I'm not in front of computer right now, I can't test it, so please back up your data before trying it , and let me know if you encounter any errors...
