Porting

In software development, porting is the process of adapting software to run in a different context. Often it involves modifying source code so that a program can run on a different platform (i.e. on a different CPU or operating system) or in a different environment (i.e. with a different library or framework). It is also describes adapting a change or feature from one codebase to another – even between different versions of the same software.[1]

Software is classified as portable if it can be hosted in a different context with no change to the source code. It might be considered portable if the cost of adapting it to a context is significantly less than the cost of writing it from scratch. The lower the cost of porting relative to the cost to re-write, the more portable it is said to be. The effort depends on several factors including the extent to which the original context differs from the new context, the skill of the programmers, and the portability of the codebase.
