382 -##__**Why This Migration Is Required:**__##
383 -
384 -* ##ChartMuseum is deprecated and will be removed.##
385 -* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
386 -* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##
387 -
388 -## Migration Steps:##
389 -
390 -1. ##Create the New OCI Repository in Rancher##
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.##
408 -
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.
410 -
411 ------
412 -
413 -## Reverting the Migration (If Needed)
414 -If you want to move an app back to the old repository:##
415 -
416 -1. Temporarily disable the new OCI repo.
417 -2. Enable the old ChartMuseum repo.
418 -3. Open the application → **Upgrade**.
419 -4. Select the chart from the old repo.
420 -5. Save.
421 -
422 -This will reconnect the app to the old repository.
423 -
424 ------
425 -
426 -## Summary
427 -- Add new OCI repo → disable old repo → upgrade apps → reconnect to OCI repo.
428 -- After upgrade, apps no longer track versions from the old repository.
429 -- Old repository will stop functioning after ChartMuseum shutdown, so migration is required.##

433 -If you want, I can also generate:
434 -- a shorter version (1-pager),
435 -- a diagram,
436 -- a Rancher UI screenshot guide,
437 -- or a version tailored for your team’s internal wiki.
