Cisco ASA config

Hi, I have a cisco config question.  I've given some background info (hopefully it helps)

I work for a UK subsidiary of a large Germany company.  The parent company manage the domain and we all have smpt feeds from the parent company.  My email traffic comes into a Cisco ASA 5510.  On this I have a rule that sends onto my Exchange server.

I am looking to change our network IP range from a public address (that we dont own) 200.100.10.0 (no idea why it was set up this way) to a private address 10.10.10.0.

I have looked through the config on the ASA and can see that there is only one entry for the IP address of my exchange server.

Is it simply a case of changing this IP address to my new address 10.10.10.9?  Im sure it isnt.  I'll obviously need to inform the german IT guys so that they can record the changes.

Any assistance much appreciated.
