Case Study: Migration Structure Support

Migration Support for a Structurally Fragmented Manual

Situation

  • A long-lived Word manual created by multiple authors over several years

  • Information types mixed together

  • Inconsistent hierarchy and organization

Problem

  • Content structure reflected history, not intent

  • High risk of migrating problems into a new system

  • No clear topic boundaries or hierarchy

Architectural Approach

  • Reviewed the existing manual to identify structural issues

  • Defined a target documentation structure independent of the source format

  • Provided guidance on how content should be reorganized before and during migration

Key Decisions

  • Separate mixed information into appropriate topic types

  • Redefine hierarchy based on content purpose

  • Avoid “lift and shift” migration of existing structure

Results

  • Clear target structure for migration

  • Reduced risk of structural cleanup after migration

  • Improved long-term maintainability

Why This Matters

Migration is an opportunity to fix structural problems, not preserve them. Architectural decision support ensures that documentation improves rather than degrades during system changes.
