we migrated the DNN 4.09 version to the new server and created a new DNS for it. We had copied the files from existing server to new server and also database backup and restore to new server. The server settings are similar to the old server. We had changed the portal alias from backend table to new DNS(site )name. The site is browsing but we can't able to login to the DNN or even the host login is also not working. Can you please guide us what are the changes need to be done after migration to make the login issue be resolved.
