Trying to migrate from DSL to Cable

[pjx]

I am running zimbra on a mac with os x server it is all working fine now. I am about to switch my network from DSL to Cable. Both have static IP addresses. I did not build the server, but I need to know if I need to change anything inside the server. I searched through the forums, but I couldn't find anything relevant to my situation. I will have a different static IP and a different DNS host. I can change my MX records online easy enough. Now where do I have to change these in the server.

So since I cant afford to hire a consultant I have to make this work myself.

Thanks in advance.
