I'm planning on upgrading my Exchange 2007 SP1 to SP3 . I've been using ISA 2006 to redirect OWA to Internet. Nothing is written about ISA in SP3's release note. That means nothing to worry about it, right? I suppose all settings are conserved during the upgrade, right? For example, send and receive connectors, anti-spam filters, etc. Anyway, there're so many parameters that it's impossible for me to remember everyone of them, thus impossible for me to check them all if any one of them is missing.... hope not.

That's right. you're right. Good luck with the upgrade :-)Netanel Ben-Shushan, IT Consultant & Trainer | Website (Hebrew): http://www.ben-shushan.net | IT Services: http://www.ben-shushan.net/services | Weblog (Hebrew): http://blogs.microsoft.co.il/blogs/netanelb | E-mail: msilforums@ben-shushan.net

Hi Horinius, You don't have to worry about your settings SP3 will not change any of these and for ISA neither all will stay as is right now.
