Prefered with integrated mode? Definitely...Possible with classic mode? Probably but I haven't tried it myself though. Seems like a nice time to upgrade to IIS 7+ at the same time...
I agree, you should run Integrated mode.
I prefer to set this to true to get help to avoid unnecessary stuff in my Web.config:
<system.webServer> <validation validateIntegratedModeConfiguration="true" />
we have old Episerver 6 running in classic mode iis. we are upgrading to to Episerver 7.
my question is can episerver 7 in classic mode ? is it prefered to work on Integrated ?
