371 -There are two ways to migrate your repositories:
372 -
373 -1. Direct Transition (Editing the Existing Repository)
374 - You can modify the existing repository directly:
375 -11.Change the target to “OCI Repository”.
376 -11.Update the URL as required (the repository name cannot be changed).
377 -
378 -After saving, installed apps will automatically start using the updated repository.
379 -
380 -Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
381 -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”).
382 -The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.
383 -
384 -1. Add New Repositories One by One (Recommended)
385 -
386 -This approach allows a smooth transition while the old ChartMuseum repository continues to function.
387 -You can:
388 -
389 -* Create a new OCI repository for each chart,
390 -* Keep the old ChartMuseum repo enabled during the migration,
391 -* Migrate applications gradually following the steps described in the main migration guide.
392 -
393 -This avoids disruptions and allows controlled migration.
394 -
395 -Special Case: Old Repo Targeting Multiple Chart Repos
396 -
397 -If your existing repository targets multiple chart repositories and you need the new OCI setup to behave the same way, please contact support. OCI does not support multi-chart endpoints within a single repository, and we can help you find an appropriate solution.
398 -
399 -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

410 -##__**Why This Migration Is Required:**__##
411 -
412 -* ##ChartMuseum is deprecated and will be removed.##
413 -* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
414 -* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##

416 -## Migration Steps:##
417 -
418 -1. ##Create the New OCI Repository in Rancher##
419 -11. Go to **Apps → Repositories**.
420 -11. Add a new repository of type **OCI**.
421 -11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
422 -11. Point it to the new OCI endpoint.
423 -1. ##Disable the Old ChartMuseum Repository Temporarily## 
424 -##This step ensures that Rancher resolves charts from the new OCI repo.##
425 -11. Go to **Apps → Repositories**.
426 -11. Disable the old HTTP(S)-based repository.
427 -11. Keep it disabled until the migration is done.
428 -1. ##Update Existing Applications to Use the New OCI Repo##
429 -Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
430 -11. Go to **Apps → Installed Apps**.
431 -11. Open the application that was deployed using the old repo.
432 -11. Click **Upgrade**.
433 -11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
434 -11. Choose the chart version you want to deploy (same or newer).
435 -11. Click **Upgrade**.
436 -1. ##Re-enable the Old Repository (Optional) ##
437 -If you still need the old repo for other apps, re-enable it after the migration steps above.
438 -**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

442 -## Reverting the Migration (If Needed)
443 -If you want to move an app back to the old repository:##
444 -
445 -1. Temporarily disable the new OCI repo.
446 -1. Enable the old ChartMuseum repo.
447 -1. Open the application → **Upgrade**.
448 -1. Select the chart from the old repo.
449 -1. Save.
450 -
451 -This will reconnect the app to the old repository.
