Due to data protection, it is not possible for us to migrate user data to the new service. If you want to use the new ProvStore for storing your backed up provenance documents, you will need to create an account at the new ProvStore and upload the documents following the restore instructions.

Other changes

With the impending retirement of Python 2, I have migrated the code base of ProvStore to Python 3, which is powering the new service.

In addition, ProvStore is now using Keycloak as the authentication backend, with the view that it will be the central identity management service for all our future services at

Undoubtedly, with such major changes to ProvStore, unforeseen issues will emerge. If you run into problems using the new service, please do report them and I will try to address them.
