No, OSS buckets cannot be renamed, and OSS objects cannot be migrated. To use another bucket name, we recommend that you create a bucket, migrate the objects from the source bucket to the destination (new) bucket, and then delete the metadata object and source bucket.
If the source bucket contains a small number of objects, you can copy the objects to migrate your data. For more information, see Copy objects.
If the source bucket contains a large number of objects, you can use one of the following methods to migrate your data:
Use cross-region replication (CRR) or same-region replication (SRR). For more information, see Overview or SRR overview.
Use Data Online Migration. For more information, see Background information.
Use the ossimport tool. For more information, see Overview.
