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.

383 -1. Add New Repositories One by One (Recommended)
384 -
385 -This approach allows a smooth transition while the old ChartMuseum repository continues to function.
386 -You can:
387 -
388 -* Create a new OCI repository for each chart,
389 -* Keep the old ChartMuseum repo enabled during the migration,
390 -* Migrate applications gradually following the steps described in the main migration guide.
391 -
392 -This avoids disruptions and allows controlled migration.
393 -
394 -Special Case: Old Repo Targeting Multiple Chart Repos
395 -
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.

409 -##__**Why This Migration Is Required:**__##
410 -
411 -* ##ChartMuseum is deprecated and will be removed.##
412 -* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
413 -* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##

415 -## Migration Steps:##
416 -
417 -1. ##Create the New OCI Repository in Rancher##
418 -11. Go to **Apps → Repositories**.
419 -11. Add a new repository of type **OCI**.
420 -11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
421 -11. Point it to the new OCI endpoint.
422 -1. ##Disable the Old ChartMuseum Repository Temporarily## 
423 -##This step ensures that Rancher resolves charts from the new OCI repo.##
424 -11. Go to **Apps → Repositories**.
425 -11. Disable the old HTTP(S)-based repository.
426 -11. Keep it disabled until the migration is done.
427 -1. ##Update Existing Applications to Use the New OCI Repo##
428 -Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
429 -11. Go to **Apps → Installed Apps**.
430 -11. Open the application that was deployed using the old repo.
431 -11. Click **Upgrade**.
432 -11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
433 -11. Choose the chart version you want to deploy (same or newer).
434 -11. Click **Upgrade**.
435 -1. ##Re-enable the Old Repository (Optional) ##
436 -If you still need the old repo for other apps, re-enable it after the migration steps above.
437 -**Note:** Even if a newer chart version exists in the old repository, your migrated app **will not see it**, because it is no longer connected to that repo
438 -

440 -
441 -## Reverting the Migration (If Needed)
442 -If you want to move an app back to the old repository:##
443 -
444 -1. Temporarily disable the new OCI repo.
445 -1. Enable the old ChartMuseum repo.
446 -1. Open the application → **Upgrade**.
447 -1. Select the chart from the old repo.
448 -1. Save.
449 -
450 -This will reconnect the app to the old repository.
