376		-There are two ways to migrate your repositories:
377		-
378		-1. ##Direct Transition (Editing the Existing Repository)##
379		-1*. Change the target to “OCI Repository”.
380		-1*. Update the URL as required (the repository name cannot be changed).
381		-1*. After saving, installed apps will automatically start using the updated repository.
382		-1*. (% class="box" %)
383		-(((
384		-Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
385		-If your old repository included several charts (for example “bitbucket” and “jira”), then after switching to OCI you can only target one chart (e.g. “bitbucket”).
386		-The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.
387		-)))
388		-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:
389		-1*. Create a new OCI repository for each chart,
390		-1*. Keep the old ChartMuseum repo enabled during the migration,
391		-1*. Migrate applications gradually following the steps described here.
392		-1*. This avoids disruptions and allows controlled migration.
393		-1. //Special Case: Old Repo Targeting Multiple Chart Repos//
394		-If your existing repository targets multiple chart repositories and you need the new OCI setup to behave the same way, please **contact support.**
395		-
396		-To ensure a smooth transition, we recommend to **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase. If you don't w

398		-| Term | Meaning
399		-| **Old Repository** | The existing HTTP/HTTPS Harbor ChartMuseum repository.
400		-| **New Repository** | The new OCI-based Helm chart repository created for your project (e.g. `<chart-repo-name>` in `<pkey>-helm`).
401		-
402		-##__**Why This Migration Is Required:**__##
403		-
404		-* ##ChartMuseum is deprecated and will be removed.##
405		-* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
406		-* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##
407		-
408		-## Migration Steps:##
409		-
410		-1. ##Create the New OCI Repository in Rancher##
411		-11. Go to **Apps → Repositories**.
412		-11. Add a new repository of type **OCI**.
413		-11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
414		-11. Point it to the new OCI endpoint.
415		-1. ##Disable the Old ChartMuseum Repository Temporarily##
416		-##This step ensures that Rancher resolves charts from the new OCI repo.##
417		-11. Go to **Apps → Repositories**.
418		-11. Disable the old HTTP(S)-based repository.
419		-11. Keep it disabled until the migration is done.
420		-[[image:1765548124989-482.59.06.png||height="152" width="485"]]
421		-1. ##Update Existing Applications to Use the New OCI Repo##
422		-Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
423		-11. Go to **Apps → Installed Apps**.
424		-11. Open the application that was deployed using the old repo.
425		-11. Click **Edit/Upgrade**.
426		-[[image:1765548598644-830.png||height="138" width="811"]]
427		-11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
428		-11. Choose the chart version you want to deploy (same or newer).
429		-11. Click **Upgrade**.
430		-1. ##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		-**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
433		-
434		-----
435		-
436		-## Reverting the Migration (If Needed)
437		-If you want to move an app back to the old repository:##
438		-
439		-1. Temporarily disable the new OCI repo.
440		-1. Enable the old ChartMuseum repo.
441		-1. Open the application → **Upgrade**.
442		-1. Select the chart from the old repo.
443		-1. Save.
444		-
445		-This will reconnect the app to the old repository.
