369 -##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)**.##
370 -
371 -To ensure a smooth transition, we recomment should **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.
372 -
373 -We will make your charts available in the corresponding new `<pkey>-helm` OCI projects.

381 -| **Old Repository** | The existing HTTP/HTTPS ChartMuseum repository. |
382 -| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`). |

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**.##

391 ------
392 -
393 -## Migration Steps##
394 -
395 -### 1. Create the New OCI Repository in Rancher##
396 -
397 -1. Go to **Apps → Repositories**.
398 -2. Add a new repository of type **OCI**.
399 -3. Name it exactly like your old repo name (e.g. `<chart-repo-name>`).
400 -4. Point it to the new OCI endpoint.
401 -
402 ------
403 -
404 -### 2. Disable the Old ChartMuseum Repository Temporarily
405 -This step ensures that Rancher resolves charts from the new OCI repo.##
406 -
407 -1. Go to **Apps → Repositories**.
408 -2. Disable the old HTTP(S)-based repository.
409 -3. Keep it disabled until the migration is done.
410 -
411 ------
412 -
413 -### 3. Update Existing Applications to Use the New OCI Repo
414 -Applications deployed with the old repository still contain the old repo name in their metadata.
415 -You must upgrade them once to transition.##
416 -
417 -1. Go to **Apps → Installed Apps**.
418 -2. Open the application that was deployed using the old repo.
419 -3. Click **Upgrade**.
420 -4. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
421 -5. Choose the chart version you want to deploy (same or newer).
422 -6. Click **Upgrade**.
423 -
424 -After this upgrade:
425 -- Your application is now linked to the **new OCI repository**.
426 -- Rancher will show upgrade notifications only for versions available in the new repo.
427 -
428 ------
429 -
430 -### 4. Re-enable the Old Repository (Optional)
431 -If you still need the old repo for other apps, re-enable it after the migration steps above.##
432 -
433 -> 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.
434 -
435 ------
436 -
437 -## Reverting the Migration (If Needed)
438 -If you want to move an app back to the old repository:##
439 -
440 -1. Temporarily disable the new OCI repo.
441 -2. Enable the old ChartMuseum repo.
442 -3. Open the application → **Upgrade**.
443 -4. Select the chart from the old repo.
444 -5. Save.
445 -
446 -This will reconnect the app to the old repository.
447 -
448 ------
449 -
450 -## Summary
451 -- Add new OCI repo → disable old repo → upgrade apps → reconnect to OCI repo.
452 -- After upgrade, apps no longer track versions from the old repository.
453 -- Old repository will stop functioning after ChartMuseum shutdown, so migration is required.##
454 -
455 ------
456 -
457 -If you want, I can also generate:
458 -- a shorter version (1-pager),
459 -- a diagram,
460 -- a Rancher UI screenshot guide,
461 -- or a version tailored for your team’s internal wiki.
