how can i change the port used by the Edge management-server, to avoid port conflicts?

[#1]

I have requirement to configure BaaS("abs" and "abp") on the same server whether gateway(Edge) is installed. For this how can i change management-server port to avoid port conflicts? I tried changing port in webserver.properties file of management conf , then ms and abs are started but not able to login with Admin credentials. Please suggest on this asap.

@u.ganeshrao.gangoji , can you please explain what do you mean "abs" and "abp" ?

"abs" = api backend stack

"abp" = api backend portal
