Quick answer

Migrate into WhatConverts with a list inventory, field map, pilot import, dual-run week, and marketing ↔ CRM sync validation — then cut over only when the marketing team trusts the contacts. Prove one segment before you move the whole book of lists and automations.

WhatConverts migration takeaways

Lists are the product — WhatConverts tracks phone calls, forms, chats, and transactions with marketing attribution for agencies and local/lead-gen marketers. Published single-account plans (2026-08-17): Call Tracking from list price, Plus list price Pro list price Elite list price; m… A migration that moves rows but breaks suppressions or owners will burn contacts/channels and trust.
Pilot before bulk — One seller’s book or one priority segment first — fix mapping before volume.
CRM stays the system of record — Research names Google Analytics, WordPress, and Zapier on the WhatConverts side — confirm the connectors your campaign loop depends on.
Watch packaging during cutover — Researched plans: Call Tracking, Plus, Pro, Elite. Never invent list prices here — confirm seats, contacts/channels, and quote terms on /pricing/whatconverts/.

Bring these questions to every demo

Ask vendors to show the workflow live, not just describe it.

1Inventory source objectsLists, automations, automation books, suppressions, owners.
2Sign off the field mapTitles, emails, phones, owners, do-not-contact.
3Run a pilot importOne segment; fix mapping before bulk.
4Dual-run one weekWhatConverts is write-path; old tool is read-only.
5Validate with the marketing teamSpot-check contacts and marketing ↔ CRM sync before cutover.

1. Inventory lists and map fields before any import

WhatConverts migration diagram 1. — Map meanings and owners before volume into WhatConverts.

Inventory contacts, segments, campaigns, automation workflows, suppressions, and owners in the source tool.
Map each critical field to WhatConverts (and to CRM where sync will write).
Decide archive-only fields — do not invent destinations for junk.
Remap departed owners to living users before volume. Worked example: a 6-person growth marketing team discovers 14% of open automation steps still owned by a departed AE; they remap those owners in the sheet before any WhatConverts import.

2. Pilot one segment — then scale

WhatConverts migration diagram 2. — Fix mapping on one WhatConverts segment before you scale.

Choose one seller’s book or one priority segment (tens to low hundreds of records).
Import into WhatConverts, then spot-check emails, phones, titles, and suppressions.
Run one campaign or automation session from the pilot set.
Confirm CRM received the activities before approving bulk. Worked example: a 6-person growth marketing team pilots Sam’s mid-market list into WhatConverts, finds two title mappings wrong, fixes the map, and only then schedules the full import.

3. Dual-run one week with a hard write rule

WhatConverts migration diagram 3. — One dual-run week is enough if WhatConverts is truly the write path.

Declare WhatConverts the write path for new lists and outreach.
Old tool becomes read-only history — no new campaigns there.
If anyone starts a new campaign in the old tool, restart the dual-run week.
End the week with seller sign-off on 20 random contacts. Worked example: a 6-person growth marketing team prints the rule on Slack: “New outreach only in WhatConverts.” Two violations restart the clock; week two is clean and they cut over.

4. Cut over after marketing ↔ CRM sync and pod validation

WhatConverts migration diagram 4. — Cut over to WhatConverts only after the marketing team trusts contacts and marketing ↔ CRM sync.

Validate marketing ↔ CRM sync for creates and activities.
Freeze legacy write access.
Archive or export legacy lists you still need for audit.
Schedule the first post-cutover usage review. Worked example: a 6-person growth marketing team cutovers only after Priya and Sam each confirm five contacts and their last outreach appear correctly in CRM from WhatConverts.

5. Inventory what must move into WhatConverts

List users, historical records, templates, and integrations that must survive migration. Mark nice-to-have exports you can leave behind.

Worked example: Agencies and local marketers needing call/form attribution migrates active records only and archives the rest as read-only exports.

6. Run parallel cutover with a rollback path

Keep the old system read-only until WhatConverts passes non-admin proof. Name a rollback owner and maximum parallel window.

Worked example: Agencies and local marketers needing call/form attribution caps parallel run at two weeks with daily checkpoint notes.

7. Verify counts and permissions after import

Reconcile user counts, role permissions, and a sample of migrated records. Research lists Google Analytics, WordPress, and Zapier for WhatConverts. Confirm which are native vs API before go-live.
