Hi! We have an old site, with a array CAS\HUB\DAG E10 servers and the OWA-publication through TMG. There is also a new site and which will develop a new UAG-array and a new array CAS\HUB\DAG E10 on which users mailbox will be gradually transferred. It is necessary to throw the Internet-channel from an old site in new and thus there is a problem of a proxy-request to OWA to servers in an old site (current - redirect). Mailboxes which already in a new site, are accessible through a new UAG-array. Question: whether it is necessary to do at such proxy-request any additional configuration in the publication? In particular, whether it is necessary to change basic authentication for something other (CKD etc)? Thanks !
