How can I configure IIS 8.0 and Primepush

Did you check the existing answer for 5.0 and 5.1? I assume that you problem has nothing to do with IIS 8 - but with the primefaces and ivy version you use.

http://answers.axonivy.com/questions/10/can-i-use-primepush-in-xpert-ivy

Yes, I have implemented like the existing answer for 5.1 and it works fine when i run primepush directly through Ivy server link.

I just got a problem when I run primepush through IIS.
It showed a message in chrome console:
WebSocket connection to 'ws://winserver2012:8019/ivy/primepush/Inbox/810/FL01/12989?X-Atmosphere-tracking-id=0&X-Atmosphere-Framework=2.2.0-javascript&X-Atmosphere-Transport=websocket&X-Atmosphere-TrackMessageSize=true&X-Cache-Date=0&X-atmo-protocol=true' failed: Error during WebSocket handshake: net::ERR_CONNECTION_RESET

can you provide more informations out of the atmosphere framework?

I'd try to raise the log level for Atmosphere. To do so copy the following xml into your engine/configuration/log4jconfig.xml:

<category name="org.atmosphere.cpr.AtmosphereFramework" class="ch.ivyteam.log.Logger">
    <priority value="INFO"/>
</category>
