Both are currently on version 4.0(6). I would like to upgrade these one at a time. Is there any problem with upgrading one to 4.1(2) then waiting a week till I upgrade the second one. I always worry about a big jump when they are in an active active config with multiple context.</P><P></P><P>Thanks</P><P>Gary</P> Mon, 11 Mar 2019 18:22:11 GMT gm-douglas 2019-03-11T18:22:11Z FWSM IOS version https://community.cisco.com/t5/network-security/fwsm-ios-version/m-p/1433517#M637869 <P>I have two FWSM's in an active active configuration.

Both units will complain that the other unit is running a diff. code than itself.</P><P>I have seen people do this often times.&nbsp; Downgrading or upgrading is pretty simple. You can upgrade them both to 4.1.6 and if that doesn't work for some reason then you can downgrade both of them to 4.0.6. </P><P></P><P>-KS</P></BODY></HTML> Fri, 06 Aug 2010 20:00:24 GMT https://community.cisco.com/t5/network-security/fwsm-ios-version/m-p/1433518#M637927 Kureli Sankar 2010-08-06T20:00:24Z
