Keep shipping while you modernize.

Bosun helps your team choose the path, move one slice at a time, and prove behavior before each slice moves into real use.

Most of the work happens around the code change.

In one study, developers spent 58% of their time understanding software. During a modernization, your team also tests, compares, and reviews each slice before promotion.

58%

of developer time in one study went to understanding software.

Read the study
  1. UnderstandCode, domain, runtime
  2. ChangeOne small behavior
  3. ValidateTests, effects, review

Prepare the path. Then move one slice.

Bosun turns the first four stages into a migration path. The last two repeat as your team learns.

Build the migration path

  1. AssessFind the seam
  2. StrategizeChoose both architectures
  3. Map patternsMake translation consistent
  4. BootstrapPrepare coexistence and rollback

Repeat one slice at a time

Choose slicesPick the next small behavior
Migrate one sliceProve, route, and observe

Evidence updates the backlog

Each system has its own seams, patterns, and proof needs. Bosun runs the repeatable work. Your engineers approve the migration path and each promotion.

The method follows behavior across languages and dialects. Customer case · Technical case
