Cisco ASA config for new public IP addresses

We are moving onto a different ISP and thus our public IP addresses are changing.  We have about 8 of them.  I was wondering if the change is as simple as mapping out current public IP addresses to the new ones, then doing a "find and replace" through a saved copy of the config file.  Then upload the config file to the ASA with a name, and set the ASA to boot to that config?
Then if all goes well, I'll save the new running config to the startup-config file.

I'll of course make the changes to DNS as well.

Just wondering if it's that simple or if I'm missing something on the ASA.

it is that easy, just make sure you do the same for the default gateways and the subnet masks
