++=== Migrating chart repositories in rancher to new OCI Repository format ===
++
++As chartmuseum is getting deprecated, after the full migration the charts will be deleted from chartmuseum and old repositories won't be working in rancher anymore. For smooth migration, we recommend adding an OCI Repository along with the olf http(s) based one during migration process, as we will make the charts available in the new <pkey>-helm projects for you. If you deployed the apps using the previous chart repo, the app contains chart repo name in its labels, so transition process need few steps. First, create <chart-repo-name> OCI repo in rancher. Then disable the old repo for some time in your repositories. After that, go the the application which was deployed using the chart from older repo anf click upgrade, there you will see all available chart repository in your cluster. Scroöö till the end till you find the new repo, choose the chart with the same or different version, and click update. Now you app is connected to new oci repositories and will show upgrade sign when a new version is available. Enable the old repo if you still use it. After this process, even if a new version for the app is availalbe in old repository, you won't see it as its not connected to it anymore. To change it, repeat the previous procees in revet.
