I currently have an SQL Server hosting two production instances which have numerous web apps accessing them. As far as I know, none of these apps are using a specific port in their connection strings, nor am I aware if this even matters.

My questions is, what are the implications of assigning theses instances to static ports? **Will this break my apps?** Are there other adjustments I need to make or consider before doing this?

Reason for asking? My infrastructure team has requested that I assign static ports for the purpose of assigning SPNs for Constrained Delegation rights. Thanks. ;)
