We are using a s3 bucket as a shared server for assets for a creative team. We are migrating to a new bucket and would like to move over folders. The new bucket is already in use.

Is there a way to sync without overwriting files? Currently using CLI.

aws s3 sync bucket1 bucket2 (this will take all of bucket1 and overwrite if it is on bucket2 even if the file on bucket2 is newer)

--exact-timestamp is not working for our use. Ideally similar to the win explore function of "do you want to replace the file at the destination skip/yes/no
