Most current browsers are able to access via the secure method.
Pages cannot have a combination of secure and insecure methods. Therefore, pages that may currently exist under the insecure root will have to be moved. This may cause counters, etc., to be reset. Since the general design style used by most people is to have both a secure and insecure version of pages this should not be an issue.
