371		-There are two ways to migrate your repositories:
372		-
373		-1. ##Direct Transition (Editing the Existing Repository)##
374		-1*. Change the target to “OCI Repository”.
375		-1*. Update the URL as required (the repository name cannot be changed).
376		-1*. After saving, installed apps will automatically start using the updated repository.

379		-Important limitation: OCI repositories must point directly to a single chart repository, not to a parent folder.
380		-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”).
381		-The other charts will no longer receive updates through this repo, and you will still need to create additional repositories for each individual chart.
382		-)))
383		-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:
384		-1*. Create a new OCI repository for each chart,
385		-1*. Keep the old ChartMuseum repo enabled during the migration,
386		-1*. Migrate applications gradually following the steps described here.
387		-
388		-This avoids disruptions and allows controlled migration.

390		-Special Case: Old Repo Targeting Multiple Chart Repos
391		-
392		-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.
393		-
394		-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

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

405		-##__**Why This Migration Is Required:**__##
406		-
407		-* ##ChartMuseum is deprecated and will be removed.##
408		-* ##Applications deployed from old repos keep a reference to that repo inside their labels.##
409		-* ##Without updating the application to point to the new OCI repo, **Rancher will not detect new chart versions from new repository**.##

411		-## Migration Steps:##
412		-
413		-1. ##Create the New OCI Repository in Rancher##
414		-11. Go to **Apps → Repositories**.
415		-11. Add a new repository of type **OCI**.
416		-11. Name it similarly to your old repo name (e.g. `<chart-repo-name>-oci`). You can't name it the same.
417		-11. Point it to the new OCI endpoint.
418		-1. ##Disable the Old ChartMuseum Repository Temporarily##
419		-##This step ensures that Rancher resolves charts from the new OCI repo.##
420		-11. Go to **Apps → Repositories**.
421		-11. Disable the old HTTP(S)-based repository.
422		-11. Keep it disabled until the migration is done.
423		-1. ##Update Existing Applications to Use the New OCI Repo##
424		-Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition.
425		-11. Go to **Apps → Installed Apps**.
426		-11. Open the application that was deployed using the old repo.
427		-11. Click **Upgrade**.
428		-11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**.
429		-11. Choose the chart version you want to deploy (same or newer).
430		-11. Click **Upgrade**.
431		-1. ##Re-enable the Old Repository (Optional) ##
432		-If you still need the old repo for other apps, re-enable it after the migration steps above.
433		-**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

437		-## Reverting the Migration (If Needed)
438		-If you want to move an app back to the old repository:##
439		-
440		-1. Temporarily disable the new OCI repo.
441		-1. Enable the old ChartMuseum repo.
442		-1. Open the application → **Upgrade**.
443		-1. Select the chart from the old repo.
444		-1. Save.
445		-
446		-This will reconnect the app to the old repository.
