If you make sure you have all the firewall settings correct, and you have all the information about users, urls and information about the content that are going to be mirrored, you should be able to configure it in a couple of hours. But, I can guarantee that you will get access or configuration errors during setup, so I would guess that you use 4-8 hours. Depending on your luck ;) (That's based on 4.X mirroring, I haven't done any mirroring in CMS) -- Lars Øyvind Bodahl www.epinova.no
