Create a diagram (or table or written description) that illustrates the flow of information on your system. This serves as a reference for the migration team. Include the following information:
Servers, including file, print and application servers. For each server, include:
Machine name
IP address
Sybase name and aliases
Clients
Applications
Number of users
Network
Protocols
Gateways
Routers, brouters, bridges
For example, you can create a diagram like Figure 1-1 which shows a high-level view of the Acme Brokerage, a firm with business in several cities and two main computing centers:
Figure 1-1: Diagram of brokerage information-flow
You can write a high-level business description in addition to or instead of a diagram.
