304		-)))
	368	+As chartmuseum is getting deprecated, after the full migration the charts will be deleted from chartmuseum and old repositories won't be working in rancher anymore. For smooth migration, we recommend adding an OCI Repository along with the olf http(s) based one during migration process, as we will make the charts available in the new <pkey>-helm projects for you. If you deployed the apps using the previous chart repo, the app contains chart repo name in its labels, so transition process need few steps. First, create <chart-repo-name> OCI repo in rancher. Then disable the old repo for some time in your repositories. After that, go the the application which was deployed using the chart from older repo anf click upgrade, there you will see all available chart repository in your cluster. Scroöö till the end till you find the new repo, choose the chart with the same or different version, and click update. Now you app is connected to new oci repositories and will show upgrade sign when a new version is available. Enable the old repo if you still use it. After this process, even if a new version for the app is availalbe in old repository, you won't see it as its not connected to it anymore. To change it, repeat the previous procees in revet.

311		-There are two ways to migrate your repositories:
312		-
313		-1. ##Direct Transition (Editing the Existing Repository)##
314		-1*. Change the target to “OCI Repository”.
315		-1*. Update the URL as required (the repository name cannot be changed) and add a new robot account for hel, check documentation above
316		-1*. After saving, installed apps will automatically start using the updated repository.

319		-Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.

321		-The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.
322		-)))
323		-1. Add New Repositories One by One (Recommended), preserve the old one till the end. This approach allows a smooth transition while the old ChartMuseum repository continues to function. You can:
324		-1*. Create a new OCI repository for each chart,
325		-1*. Keep the old ChartMuseum repo enabled during the migration,
326		-1*. Migrate applications gradually following the steps described here.
327		-1*. This avoids disruptions and allows controlled migration.

329		-1. //Special Case: Old Repo Targeting Multiple Chart Repos//
330		-If your existing repository targets multiple chart repositories and you need the new OCI setup to behave the same way, please **contact support.**

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

338		-##__**Why This Migration Is Required:**__##
339		-
340		-* ##ChartMuseum is deprecated and will be removed.##
341		-* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
342		-* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##
343		-
344		-## Migration Steps:##
345		-
346		-1. ##Create the New OCI Repository in Rancher##
347		-11. Go to **Apps → Repositories**.
348		-11. Add a new repository of type **OCI**.
349		-11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). __**You can't name it the same and can't rename it later.**__
350		-11. Point it to the new OCI endpoint.
351		-1. ##Disable the Old ChartMuseum Repository Temporarily##
352		-##This step ensures that Rancher resolves charts from the new OCI repo.##
353		-11. Go to **Apps → Repositories**.
354		-11. Disable the old HTTP(S)-based repository.
355		-11. Keep it disabled until the migration is done.
356		-[[image:1765548124989-482.59.06.png||height="152" width="485"]]
357		-1. ##Update Existing Applications to Use the New OCI Repo##
358		-Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
359		-11. Go to **Apps → Installed Apps**.
360		-11. Open the application that was deployed using the old repo.
361		-11. Click **Edit/Upgrade**.
362		-[[image:1765548598644-830.png||height="138" width="811"]]
363		-11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**. Or enter the chart name in search bar:
364		-[[image:1765548750604-334.png||height="293" width="308"]]
365		-11. Choose the chart version you want to deploy (same or newer).
366		-11. Click **Upgrade**.
367		-1. ##Re-enable the Old Repository (Optional) ##
368		-If you still need the old repo for other apps, re-enable it after the migration steps above.
369		-**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
370		-
371		-##If you want to move an app back to the old repository:##
372		-
373		-1. Temporarily disable the new OCI repo.
374		-1. Enable the old ChartMuseum repo.
375		-1. Open the application → **Upgrade**.
376		-1. Select the chart from the old repo.
377		-1. Save.
378		-
379		-This will reconnect the app to the old repository.
