You can change the settings using the S3_STORAGE_BUCKET and S3_STORAGE_REGION to point to a fresh bucket at any point in time. From that point, LogScale will write new files to that bucket while still reading from any previously-configured buckets. Existing files already written to any previous bucket will not get written to the new bucket. LogScale will continue to delete files from the old buckets that match the file names that LogScale would put there.
