All devices are in a group to control config other than time. Can I upgrade only the central waas and one other waas to test the upgrade? I have one waas remote at about 90 miles so I can get there in case of disaster. I want to wait on the others to make sure there are no problems. We are using all wccp redirection and virtual blades</P><P></P><P></P><P>Sent from Cisco Technical Support iPad App</P> Tue, 22 Nov 2011 05:10:45 GMT cgarringer 2011-11-22T05:10:45Z upgrade procedure https://community.cisco.com/t5/application-networking/upgrade-procedure/m-p/1871674#M36498 <P>We are on 4.2.1 and I need to upgrade to support exchange 2010.

However, it's not recommended, so I would strongly suggest you to proceed with the upgrade of the rest of the network as soon as possible. </P><P></P><P>Regards</P><P></P><P>Daniel</P></BODY></HTML> Tue, 22 Nov 2011 10:20:55 GMT https://community.cisco.com/t5/application-networking/upgrade-procedure/m-p/1871675#M36499 Daniel Arrondo Ostiz 2011-11-22T10:20:55Z
