Redirect to a different IP address on Cisco ASA

We are moving to a new Data Center.  

We are looking to minimize down time of course.

Is there a way to redirect incoming IP requests to another external IP address?

The thinking behind this is if someone tries to access our site before their/our DNS data is updated, I would like my ASA to forward the request to the new IP.  

Is this possible, if so how would you do it?

Do you run your own DNS for your domain?   If you do you could tweak the update interval for something extremely low, like 15 minutes to force updates from your list.    Do that ahead of time (if your current interval is 5 days, do it 6 days before), that way all cached entries on all servers will start updating every 15.    

The day you move, you should see dns updates to other servers very quickly.   Except for those servers that have a limit on how frequently they update.  

AFter all is moved, then go back to the standard update interval.  


Another option is to leave a single host running on the old IP range do do redirects to the new web host at the new site.    Not too expensive if you leave it for 2 weeks or so.  


The ASA is not a router and cannot route packets back into the same interface like a router on a stick scenario.

That is what I feared.

I had already planned out DNS as you indicated, but sometime DNS servers don't listen to the refresh parameter.

I can't run the Site at both sites as it is Dynamic and data would get out of sync.

Thanks though
