I have a client who is changing their ISP in a few weeks, they are a midsize company and have about 60 employees.
They currently host their web-server, AS2 connection, Exchange server, RDP sessions, and their application on 2 local servers.
If they change their ISP then their static WAN IP address will change, what do I need to do in preparation for the ISP switch?
Will all the information about their port forward and their website be retained by the router or will there need to be changes in the router settings.
What about their DNS information and name server information that is hosted by godaddy, will this information need to be updated as well? I am assuming it will need to be updated.
Please let me know of anything I need to be prepared for before they make this change.
