Keep it disabled until the migration is done. 425 +1. ##Update Existing Applications to Use the New OCI Repo## 426 +Applications deployed with the old repository still contain the old repo name in their metadata. You must upgrade them once to transition. 427 +11. Go to **Apps → Installed Apps**. 428 +11. Open the application that was deployed using the old repo. 429 +11. Click **Upgrade**. 430 +11. In the list of available chart repositories (scroll to the bottom), select the **new OCI repository**. 431 +11. Choose the chart version you want to deploy (same or newer). 432 +11. Click **Upgrade**. 433 +1. ##Re-enable the Old Repository (Optional) ## 434 +If you still need the old repo for other apps, re-enable it after the migration steps above. 435 +**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 + 437 +---- 438 + 439 +## Reverting the Migration (If Needed) 440 +If you want to move an app back to the old repository:## 441 + 442 +1.
