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.**

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.

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

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.
