Rolling out product changes without conflicting legacy offerings

How do you roll out new product rules without inconsistently handling existing offers?

New rules are published as a separate product version and only apply from a defined effective date. Existing offers retain their agreed-upon status or are migrated via an explicitly approved migration path.

Clear Scope

1. All changed rules and their impact on offers, operations, and contracts are compared.

2. The new version has an effective date and clear rules for new, open, and ongoing orders.

3. Test orders from each group check documents, calculations, delivery, and subsequent changes before release.

Retroactive Change

• Retroactive Change – A centrally edited product overwrites services from already accepted offers.

• Parallel Shadow Versions – Sales copies old documents because the system no longer offers a valid legacy version.

• Partial Migration – Price changes to the new version, while scope or acceptance remains with the old model.

Legacy Decision

Case review: “Retroactive amendment”

A new product version includes a different release step and an adjusted price. New offers incorporate both changes; an already accepted order remains completely unchanged until a documented migration is agreed upon.

Unique Version

• Unique Version Every offer and order references an immutably identifiable performance status.

• Clear Scope The effective date and affected channels define when new rules are first applied.

• Legacy Decision For existing contracts, it is documented whether grandfathering, an option to migrate, or mandatory migration applies.

Conclusion: Product changes without legacy offering chaos

Versioning protects the product from conflicting mixed versions. A change is only rolled out cleanly when each version is handled unambiguously.
