Quick answer

Migrate to Close by inventorying legacy crm fields, mapping them to Close objects, rehearsing a freeze window, and validating WhatsApp Business, Slack before reopening writes.

  • Inventory → map → rehearse → cut over → reopen
  • Highest risk: Growth (list price annual) and Scale (list price annual) per-user pricing is high versus pipeline-only CRMs; calling usage and premium phone lines add cost.
  • Success signal: contact management works for the pilot cohort

Close migration takeaways

  • Map to what this product supports — Close research supports contact management, lead management, pipeline management, and deal management — your object model has to land inside that, not inside your old CRM's shape.
  • Pilot beats big-bang — One successful Close import of a single owner's deals teaches more than a weekend bulk load.
  • Stage meaning is the real migration — Columns copy easily; “what qualified means” does not. Agree stage definitions before mapping.
  • Custom structure has limits — Custom fields is researched across every Close plan we snapshot.
  • Keep an exit copy — Retain source exports until Close passes seller spot-checks — and ask the export question before you sign, not at renewal.
  • Verify tooling, do not assume it — Import formats, record limits, and API behaviour belong in Close documentation. Our pricing snapshot records a 14-day trial on Solo, Essentials, and Growth — confirm current terms on the Close pricing page before you build a schedule around it.

Frequently asked questions

  • Can we migrate everything into Close at once?

    You can, but you should not. Decision rule: pilot one owner's book, fix the map, then scale. Bulk-importing an unvalidated map is the most common reason a CRM rollout loses seller trust.

  • Which objects should we move first?

    Companies, then people, then open deals, then recent activities — parents before children. contact management, lead management, pipeline management, and deal management are the Close anchors in our research; old closed history can stay in an archive export.

  • How do we map custom fields into Close?

    Custom fields is researched across every Close plan we snapshot. Recreate a field only when someone can name the decision or report that depends on it; everything else goes to the archive CSV.

  • How long should the dual-run last?

    One week is usually right: long enough to catch mapping defects, short enough that people actually switch. Freeze the old system for edits during that week or you will migrate twice.

  • Who should own the migration?

    The Close admin owner runs the mechanics; a sales champion owns stage meaning; each seller validates their own book. Not an intern alone with a CSV.

  • What do we validate before cutting over to Close?

    Deal counts by owner, every open deal has an owner and stage, contacts resolve to companies, no duplicates in the top accounts, activity dates are real rather than import dates, and required fields are populated. Then seller sign-off.

  • What about getting data back out later?

    Ask before you sign: which objects export, in what format, whether notes and attachments come along, and what happens to data after cancellation. Keep your pre-migration exports either way.

  • What should I do next?

    Run the Close setup guide in parallel with the pilot so the target workspace is ready, then follow the implementation guide's 30/60/90 gates after cutover.

1. Close migration cutover playbook

  • Field inventory

    Export legacy fields that power contact management, lead management, pipeline management and mark must-map vs archive.

  • Rehearsal load

    Run a non-prod load into Close; measure match rates before the freeze.

  • Production freeze

    Freeze legacy writes; cut over; validate WhatsApp Business; then reopen.

Migrations fail from optimistic timelines — not from missing motivation.

Migrate to Close?

  1. 1Migrate when Inside sales and outbound teams that live on phone/email/SMS outweigh migration cost
  2. 2Delay if this limitation hits cutover: Growth (list price annual) and Scale (list price annual) per-user pricing is high versus pipeline-only CRMs; calling usage and premium phone lines add cost.
  3. 3If Close mapping is poor, compare destination fit with Pipedrive before moving data twice

Close migration mistakes

  • No freeze window

    Dual-writing without a freeze creates irrevocable duplicates.

  • Integrations last

    Wire WhatsApp Business in rehearsal — not on Monday morning after cutover.

  • Data risk 1

    Growth (list price annual) and Scale (list price annual) per-user pricing is high versus pipeline-only CRMs; calling usage and premium phone lines add cost.

  • Data risk 2

    Advanced Chloe automation/workflows and predictive dialing depth are concentrated on Growth and Scale.

  • Data risk 3

    Calling is usage-based; AI credits are pooled monthly with plan caps and no rollover.
