You can do the fast transition - edit already existing repository – choose //Target: OCI repository //and adapt the url (__repo name can't be changed__), then the installed apps will pick app the repo change automatically. The problem is that the OCI repository recommends to target chart repos in the url, not the whole folder anymore. That means if you deployed previously different apps using the old repo, for example "bitbucket" and "jira", now you can only target one repo, for example "bitbucket" 372 372 373 - Wewillmakeyourchartsavailable inthecorrespondingnew`<pkey>-helm`OCIprojects.375 +To ensure a smooth transition, we recommend to **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.
