  There are two ways to migrate your repositories:

  Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
  If your old repository included several charts (for example “bitbucket” and “jira”), then after switching to OCI you can only target one chart (e.g. “bitbucket”).
  The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.

++1. Add New Repositories One by One (Recommended), preserve the old one till the end. This approach allows a smooth transition while the old ChartMuseum repository continues to function. You can:
++1*. Create a new OCI repository for each chart,
++1*. Keep the old ChartMuseum repo enabled during the migration,
++1*. Migrate applications gradually following the steps described here.
++1*. This avoids disruptions and allows controlled migration.
