371 -To ensure a smooth transition, we recommend to **add an OCI-based repository alongside the existing ChartMuseum repository** during the migration phase.
371 +There are two ways to migrate your repositories:
372 372  
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).

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.
