Cisco - ASA 5500 - Cannot change

What is the CLI command to change the Inside interface IP address/network from 192.168.1.1 to 192.168.2.254?
When I use the ASDM console, and change the network address, I cannot apply the changes due to the change in network address which does not allow me to change the network address.
I am (obviously) not a cisco guy but need to do this config in a rushed manner...
thanks

If you can ssh to the ASA, you can login and type these commands:

con t
interface Ethernet0/1
 ip address 192.168.2.254.255.255.0

You can connect using Cisco console cable and Hyperterminal/Putty software and change IP address using CLI

If you ssh to ASA on inside interface and change its ip address you will lose connection to ASA

The issue is that you are connected to the inside interface and want to change that some interface.   The ASDM will not let you do that.  

You can use SSH to the port, ASDM from another interface, or a console cable to make those changes.

You can ssh to the outside interface of the ASA and type those commands.

@MikeKane
if i understand you correctly i can do the following to change this...
- Configure Outside Int (port 0) to 192.168.3.1
- Manually configure my nic to the 192.168.3.x network.
- plug into the Outside interface
- log on to the device from the outside interface
- change the inside interface

is that correct?

Typically for the ASA to be useful, you already have an outside IP address. This usually will be a public IP address. Check with your ISP to provide this information.

You can also setup outside to get DHCP address.

Just for the purpose of reconfiguring your inside interface, you can temporary setup outside interface to 192.168.3.1 just as you described. You also need to allow management access from outside as well:
ssh 0.0.0.0 0.0.0.0 outside
http 0.0.0.0 0.0.0.0 outside
