hello,
I have a Cisco ASA 5510. We currently use it at our main site but we're going to an MPLS setup with a co-location site provided by the ISP. Currently my ASA is setup as follows

Internet T-1
    |
    |
Global IP addresses
ASA 5510
192.168.1.5/24  
   |
   |
LAN 192.168.1.0/24


we are moving the setup to the following

Internet
  |
  |
Global IP addresses(Same as above no IP address change)
ASA 5510
10.0.0.2/24
   |
   |
10.0.0.0/24 Colocation LAN
  |
  |
10.0.0.1/24 ISP MPLS Router
  |
  |
MPLS router My company 192.168.1.5/24
  |
  |
LAN 192.168.1.0/24


hopefully the above drawing isn't too confusing. basically I have fairly decent knowledge of the ASA but I'm not an expert. Here is a list of teaks that I know I have to complete. I just want to make sure I'm not forgetting anything when I actually do the move. Just to re-iterate the internet IP address range will not change, it will just be transitioned to the new router by the ISP.

1. allow admin access from 10.0.0.0/24 LAN
2. change IP address of Ethernet0/0 from 192.168.1.5/24 to 10.0.0.2/24
3. add a route for 192.168.1.0/24 via 10.0.0.1


I think this should do it. I'm not sure about any Access List changes I need to make. Do I need to make any ACL list changes for the 10.0.0.0/24 network?

I guess that depends on wheter you have machines on the 10-net that needs access or to be accessed.  I'd assume so since you want to grant admin access from that network?

I will need access to those machines via 192.168.1.0/24. obviously I will need to add PAT translations into the ACL if I need outside access to any devices on 10.0.0.0  basically the ASA will control all internet access for several sites.

Well, it seems to be covered for the details included.  And as long as you can reach the ASA, you can always make any other adjustments needed.
If you have any other Internet connection, preferably with a static IP you might consider giving that outside access until you have verified all is good.
(Unless that can already be verified when the ASA is connected at the Colo.)
