How to Update Archival URI After Namespace Creation

Hi,

I have a question regarding archival configuration in Temporal:

Once a namespace is created with file:// URIs for history_uri and visibility_uri, is it possible to update them later to switch to a different backend (e.g., from file:// to s3://)?

I understand that archival URIs are immutable after initial set, but:

  • Is there a safe way to migrate archival storage from file to S3 for an existing namespace?
  • If not, what’s the recommended path — creating a new namespace with S3 configured and migrating workflows?
  • Will there ever be support for changing archival backends post-creation?

Appreciate any guidance. Thanks!
