Migrate the operating behavior, not just the automation steps.

Provide the active Zap inventory, owners, connected accounts, triggers, filters, paths, schedules and webhooks, redacted input/output examples, task volumes and known failures. Identify required business behavior, acceptable change windows, dependencies and the client who approves cutover. Agree target hosting, working language, time zone, support coverage, delegated permissions and data handling. Connections must be authorized for the target environment; missing capability may require approved export intake, temporary coexistence or deferral.

Agreed outputs include the inventory and dependency map, migrate/redesign/coexist/defer decisions, target workflows and connections, comparison results, cutover and rollback plan, and maintenance runbook. Validate expected outputs and business state with representative records, duplicates and dependency failures before changing trigger ownership. Each action has one execution owner; the client approves cutover and the criteria for rollback. Reverting a workflow does not undo completed business writes, so the plan names any required reconciliation or human repair and the handover owner.

A safe migration is more than recreating Zapier steps in n8n. D2 inventories the existing automation estate, maps triggers, actions, filters, paths, credentials, data ownership and business behavior, then decides what should migrate with parity, what should be redesigned, what can coexist temporarily and what should be deferred. The target n8n workflows are then built with validation, idempotency, retries, observability, recovery and staged cutover controls where required.

No. Some workflows may be low-risk and inexpensive enough to remain in Zapier, while others justify migration because they need more control, scale, direct API access, custom logic or operational visibility. D2 treats migration as an architecture decision rather than a blanket platform replacement.

Yes, but the first step is to document the actual business behavior behind those constructs. Paths, filters, delays, schedules and webhooks can often be represented in n8n, yet a direct one-to-one rebuild is not always the safest design if the original automation contains hidden state or fragile dependencies.

The migration can use staged workflow groups, controlled activation windows, idempotency keys, comparison runs, explicit ownership of triggers and rollback paths. The exact cutover method depends on whether the source system supports replay, whether duplicate actions are reversible and how business state is stored.

Yes. Coexistence can be safer than a big-bang cutover when the boundary is explicit. Each trigger and business action needs one clear owner so both platforms do not process the same event or mutate the same record independently.

Not necessarily. Software subscription costs may change, but total operating cost also includes infrastructure, implementation, monitoring, maintenance, API usage and operational ownership. D2 does not promise a fixed savings percentage; the migration decision should consider control, reliability, scale and total cost together.

Yes, where self-hosting fits the ownership and operational requirements. The target can include production infrastructure, persistence, workers, queues, credentials, monitoring and recovery controls. Hosting responsibility and infrastructure scope should be explicit in the proposal.

The client retains authority over business accounts and credentials. During migration, each connection should be re-established using an approved credential ownership model rather than blindly copying secrets. D2 can configure the target connections and document how access is controlled within the agreed scope.

Yes. In many cases redesign is the better migration outcome. The goal is to preserve required business behavior, not platform-specific implementation details. Direct APIs, webhooks, durable state, reconciliation or custom services may replace parts of the old Zapier design where that produces a more reliable operating system.

D2 scopes the engagement around the number and complexity of automations, integrations, hidden dependencies, redesign requirements, target infrastructure, validation, cutover risk and ongoing ownership. Third-party APIs, model usage, infrastructure and software fees remain separate unless explicitly included in the proposal.
