368 +ChartMuseum is being deprecated. After the migration is complete, **all harbor charts will be removed from ChartMuseum**, and **old HTTP(S)-based chart repositories will no longer work in Rancher (for internal harbor charts)**.
369 +)))
370 +
371 +To ensure a smooth transition, we recommend to **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.

375 +**We will make your charts available in the corresponding new `<pkey>-helm` OCI projects.**
376 +)))
377 +
378 +| Term | Meaning
379 +| **Old Repository** | The existing HTTP/HTTPS Harbor ChartMuseum repository.
380 +| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`).
381 +
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.##
430 +
431 +-----
432 +
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.
