We have a Minio cluster that we use as an on-premises object storage. We want to rename a bucket in it. How can I do this?

IF:
- you are running a single instance minio
- you have access to the minio volume directly
Then, yes, it is simply possible by renaming the directory directly.
mv old-bucket.mydomain.example new-bucket.mydomain.example
Explanation
Let's assume minio data is stored in /data/, and we have a bucket called old-bucket.mydomain.example. Then the bucket is stored under /data/old-bucket.mydomain.example directory. Therefore, we can simply rename the directory and it would work!
Update
Please note that, there might be some issues in case of having encryption enabled on the bucket.

Thanks, it worked for my single instance minio setup
It is not possible to rename buckets: you have to create a new bucket with the desired name, copy over your data mc cp -r minio/oldbucket minio/newbucket and delete the old bucket.

Use mc to create, mirror and delete, here with local as the instance name:
mc mb local/newbucket
mc mirror local/oldbucket local/newbucket
mc rm -r --force local/oldbucket
mc rb local/oldbucket

Renaming the directory does not alter the metadata. Use the CLI.

For me, it took a few minutes and then the metadata was updated automatically when renaming with mv in a single instance minio (version RELEASE.2025-04-08T15-41-24Z).
