Failover ASA's

I have 2 ASA configured exactly the same.  I need to change the ISP on them however, I can't do this live.  These are set to fail over and I was wondering if there's a way for me to work on the 2nd - (NOT LIVE) ASA without interrupting the 1st?  Can this be done?  I

good question.  I think what I'm going to have to do is to configure the secondary with the new ISP info, test it and copy the config once I know it's work or I can simply just change the 3 addresses I need to on the ASA.  I"m still a "baby" when it comes to Cisco and routing.  I understand the concepts but I'm not one to test live!
Your best bet would be to have someone on-site, with an independent internet connection, TeamViewer running, a console cable to the ASA(s), and you remote in and change the configuration.
I was able to finally do just this. Thanks.
