379 -Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
380 -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”).
381 -The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.

385 -This approach allows a smooth transition while the old ChartMuseum repository continues to function.
386 -You can:

388 -* Create a new OCI repository for each chart,
389 -* Keep the old ChartMuseum repo enabled during the migration,

396 -If your existing repository targets multiple chart repositories and you need the new OCI setup to behave the same way, please contact support. OCI does not support multi-chart endpoints within a single repository, and we can help you find an appropriate solution.
