The awkward old thing may be carrying the part you still need.

An established system is easy to criticize. Its inconvenient details have names, histories, and people who have complained about them for years.

Its value may be quieter: operating knowledge, customer exceptions, stable integrations, and capabilities everyone notices only when a replacement omits them.

Before choosing what to keep, separate that value from the form carrying it.

Howard Pearlmutter's Goldmine & Greenfield model frames the relationship between accumulated assets and new possibilities. At Goldman Sachs, it helped executives examine difficult legacy-migration questions. Read the model in use.

The questions are practical. Which behavior must remain? Which constraint belongs to the current implementation? Could a clearer boundary let one part change while another continues to supply value? What would a prototype have to establish?

This can open an intermediate route. It can also make a broad replacement more informed when replacement is appropriate.

The same thinking can apply to a team's expertise. New tools may change the work while making experience more useful in review, interpretation, and integration. A transition should find a way to carry that knowledge forward.

Howard's work includes large-codebase migration strategy, enterprise integration, skills transfer, and current AI-assisted development. The useful combination depends on the specific asset and the change being considered.

Keep what earns its place. First, give the existing value a fair chance to be seen.
