You would modify /etc/services. And yes a restart would be needed almost certainly. I'm not familiar with the program that you're using, but I'm never seen a program yet that monitors /etc/services for changes and then dynamically switches ports.

portreserve
PORTRESERVE(1) TCP port reservation utility PORTRESERVE(1)
NAME
portreserve - reserve ports to prevent portmap mapping them
SYNOPSIS
portreserve
DESCRIPTION
The portreserve program aims to help services with well-known ports that lie in the bindresvport range. It prevents portmap (or other
programs using bindresvport) from occupying a real service's port by occupying it itself, until the real service tells it to release the
port (generally in its init script).
It is intended that portreserve runs from an initscript of its own, and services wishing to interact with it should use portrelease.
When the portreserve daemon is started, it examines the /etc/portreserve/ directory. Each file not containing "." or "~" in its name is
considered to be a service configuration file, and must contain a service name (as listed in /etc/services) or a port number. UDP services
may be specified by appending "/udp" to the service name, and TCP services by "/tcp". Several services may be specified, one per line.
For example, /etc/portreserve/cups might contain the string "ipp" or, equivalently, "ipp/tcp" and "ipp/udp" on separate lines.
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must
first run portrelease, which instructs portreserve to release the port associated with the service.
Once all the reserved ports have been released, the daemon exits.
