	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.##
