391 +11. Go to **Apps → Repositories**.
392 +11. Add a new repository of type **OCI**.
393 +11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
394 +11. Point it to the new OCI endpoint.
395 +1. ##Disable the Old ChartMuseum Repository Temporarily##. ##This step ensures that Rancher resolves charts from the new OCI repo.##
396 +11. Go to **Apps → Repositories**.
397 +11. Disable the old HTTP(S)-based repository.
398 +11. Keep it disabled until the migration is done.
399 +1. ##Update Existing Applications to Use the New OCI Repo##
400 +##Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.##
401 +11. Go to **Apps → Installed Apps**.
402 +11. Open the application that was deployed using the old repo.
403 +11. Click **Upgrade**.
404 +11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
405 +11. Choose the chart version you want to deploy (same or newer).
406 +11. Click **Upgrade**.
407 +1. ##Re-enable the Old Repository (Optional) If you still need the old repo for other apps, re-enable it after the migration steps above.##

386 -## Why This Migration Is Required
387 -- ChartMuseum is deprecated and will be removed.
388 -- Applications deployed from old repos keep a reference to that repo inside their labels.
389 -- Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions**.##
409 + 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.
