Version Control Walkthrough (Branching Strategies) Part 5 - Servicing & Release Isolation

Continued from Version Control Walkthrough (Branching Strategies) Part 4 - Release Isolation … audit alarm we explore service and release isolation.


Explore the Servicing and Release Isolation strategy introduces servicing branches, which enables concurrent servicing management of bug fixes and service packs. This strategy evolves from the Release Isolation strategy, or more typically from the Development and Release Isolation strategy.


We will finish this walk-through with an easy and quick exercise. We will focus on demonstrating the concepts, allowing you to expand the concepts to your required level of granularity and complexity as and when needed.

Your team is notified that a servicing model for customers to upgrade to the next major release, i.e. v1 –> v2 is implemented and, in addition, the servicing model supports additional service packs per release, starting with v3. image

  • NOTE - We are going to use an arbitrary naming convention for the branches in this exercise, as we have done before. You need to invest time in defining a consistent naming convention that suits your organization and environment before you perform a branch action. Renaming branches is atypical and as an alternative you could proactively plan and introduce the servicing branch with v4 instead of injecting it into the v3 hierarchy.
  • CAUTION – Renaming branches is technically feasible, but can introduce traceability and migration challenges in the future if not done consistently. This short and simple exercise demonstrates how easyit is to quickly introduce more branches, which dramatically increase your merge maintenance and cost.

Introduce the Servicing Branch

Rename release to servicing

  • Rename the v3 branch in Solution Control Explorer to v3 servicing.image 
  • Right-click on servicing branch, select Check In Pending Changes and check in.

Add release branch

  • Right-click on servicing branch, select Branching and Merging and Branch
  • Define the Target Branch Name as $/BranchingScenarios/rel/v3 release
  • Select Branch and Yes when promoted to continue to branch
  • Right-click on BranchingScenarios folder and perform a Get Latest Version.

View hierarchy

  • Right-click on main branch in Solution Control Explorer, select Branching and Merging, and View Hierarchy


We explored the servicing and release isolation strategy, how to implement, intentionally using a very simple branching scenario. Remember that we discourage the use of branches to isolate servicing, but your requirements may force you to deploy this branching strategy and release a service pack.

That’s all folks for this series!
