371		-There are two ways to migrate your repositories:
372		-
373		-1. ##Direct Transition (Editing the Existing Repository)##
374		-11. Change the target to “OCI Repository”.
375		-11. Update the URL as required (the repository name cannot be changed).
376		-
377		-1. Direct Transition (Editing the Existing Repository).You can modify the existing repository directly:
378		-Change the target to “OCI Repository”.Update the URL as required (the repository name cannot be changed).
379		-
380		-After saving, installed apps will automatically start using the updated repository.
381		-
382		-Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
383		-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”).
384		-The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.
385		-
386		-1. Add New Repositories One by One (Recommended)
387		-
388		-This approach allows a smooth transition while the old ChartMuseum repository continues to function.
389		-You can:
390		-
391		-* Create a new OCI repository for each chart,
392		-* Keep the old ChartMuseum repo enabled during the migration,
393		-* Migrate applications gradually following the steps described in the main migration guide.
394		-
395		-This avoids disruptions and allows controlled migration.
396		-
397		-Special Case: Old Repo Targeting Multiple Chart Repos
398		-
399		-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.
400		-
401		-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

408		-| Term | Meaning
409		-| **Old Repository** | The existing HTTP/HTTPS Harbor ChartMuseum repository.

412		-##__**Why This Migration Is Required:**__##
413		-
414		-* ##ChartMuseum is deprecated and will be removed.##
415		-* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
416		-* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##
417		-
418		-## Migration Steps:##
419		-
420		-1. ##Create the New OCI Repository in Rancher##
421		-11. Go to **Apps → Repositories**.
422		-11. Add a new repository of type **OCI**.
423		-11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
424		-11. Point it to the new OCI endpoint.
425		-1. ##Disable the Old ChartMuseum Repository Temporarily##
426		-##This step ensures that Rancher resolves charts from the new OCI repo.##
427		-11. Go to **Apps → Repositories**.
428		-11. Disable the old HTTP(S)-based repository.
429		-11. Keep it disabled until the migration is done.
430		-1. ##Update Existing Applications to Use the New OCI Repo##
431		-Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
432		-11. Go to **Apps → Installed Apps**.
433		-11. Open the application that was deployed using the old repo.
434		-11. Click **Upgrade**.
435		-11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
436		-11. Choose the chart version you want to deploy (same or newer).
437		-11. Click **Upgrade**.
438		-1. ##Re-enable the Old Repository (Optional) ##
439		-If you still need the old repo for other apps, re-enable it after the migration steps above.
440		-**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

444		-## Reverting the Migration (If Needed)
445		-If you want to move an app back to the old repository:##
446		-
447		-1. Temporarily disable the new OCI repo.
448		-1. Enable the old ChartMuseum repo.
449		-1. Open the application → **Upgrade**.
450		-1. Select the chart from the old repo.
451		-1. Save.
452		-
453		-This will reconnect the app to the old repository.
