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.##

435		-- a diagram,
436		-- a Rancher UI screenshot guide,
437		-- or a version tailored for your team’s internal wiki.
