Tactical forking is a technique that can assist with restructuring or migrating from monolithic codebases to microservices. Specifically, this technique offers one possible alternative to the more common approach of fully modularizing the codebase first, which in many circumstances can take a very long time or be very challenging to achieve. With tactical forking a team can create a new fork of the codebase and use that to address and extract one particular concern or area while deleting the unnecessary code. Use of this technique would likely be just one part of a longer-term plan for the overall monolith.
