Hello fellow Thwackers, I have been assigned as a project resource to move an application to a Cloud service. The existing environment is on a flat network consisting of a web front-end, middleware, and multiple DB servers. One of my tasks is to redesign the new environment to a n-tier and identify all the application ports needed for the new firewall rules. I ran netstat -aon and used the SolarWinds Engineer's Toolset Port Mapper tool against the servers and while it did provide open TCP connections between system x and system y, the data provided is only a snap-shot in time. Wireshark is another option but the environment is too large for it to be a feasible option. So my question is this, do any of you know of migration tools or automated application discovery tools that can scan and provide application maps to show that server x talks to server y over port z? Thanks in advance for any assistance or insight.
