I have 2 web applications SharePoint 2013 one for authoring content and the other is for publishing - using cross-site publishing feature. I want to put publishing site database to Sync with DR publishing site database using always - on availability group . Every time when I do this the DR publishing web site got corrupted - not working and all connections to authoring catalogs disconnected. I can't fix DR site as the whole site after putting them in availability group is in read only mode. so how can I sync both databases with production without breaking the catalog connection and by the way DR is same like production in URLs they are exactly the same.
