Migrating to the new Agentforce Builder means proving behavior did not regress

The new builder replaces a ReAct loop with a stateful graph and Agent Script; a safe path preserves the baseline and compares tests before optimization.

Agent loop transforming into a governed graph of routes and regression tests.

Original OrbTrail analysis expanded with complementary research, practical context and verified references.

The new Agentforce Builder changes more than the interface. Legacy agents concentrate reasoning in a prompt-led ReAct loop; the new architecture organizes subagents, transitions, variables and state as a graph, with Agent Script supporting a mix of flexibility and determinism.

An upgrade creates a new version while leaving the original agent untouched, so migration does not disrupt the active version. The safest sequence is to capture current behavior, migrate without redesigning everything and run the same test suite against both versions.

Only after functional equivalence should teams harden critical routes, make transitions explicit and add observability. Agentforce DX, AiTestingDefinition and scorers help compare routing, actions and responses instead of relying solely on manual checks.

The architectural shift hidden in the migration

The legacy builder concentrates decisions in a prompt-led ReAct loop; the new model exposes subagents, transitions, variables and state in a graph. That improves control and observability, but can change routing and memory even when instructions appear equivalent. Migration review must therefore compare the transition path and retained state for each test case, not just the final answer displayed to the user.

Baseline before optimization

Safe migration starts by freezing a representative suite: common requests, ambiguous cases, refusals, escalations and sensitive actions. The first migrated version should reproduce that behavior; Agent Script improvements come later as small, comparable and reversible changes.

Objective cutover criteria

The new agent should take traffic only after matching or beating the active version on routing accuracy, correct action execution, response quality and safety. A parallel observation period, rollback owner and exposure limits reduce the risk of discovering regressions in production.
