What are the breaking changes when moving from Outreach to Salesloft

Moving from Outreach to Salesloft breaks several things you can't ignore: sequence-to-cadence logic doesn't map 1:1, API endpoints and object models differ, custom field mappings reset, and any automation wired to Outreach triggers (snippets, plugins, webhooks) won't fire in Salesloft. Most teams underestimate how much rework the data and integration layer needs before cutover.

Why the Outreach to Salesloft migration isn't a lift-and-shift

Both tools sell the same outcome — automated, multi-touch outbound — but they model that work differently. Outreach calls its workflows sequences; Salesloft calls them cadences. The vocabulary swap is the easy part. The structural differences are where pipelines, reporting, and rep behavior quietly break.

Treat this like a system migration, not a settings copy. Audit before you export, and test in a sandbox cadence before you flip reps over.

1. Sequence and cadence logic doesn't map 1:1

This is the biggest breaking change. Outreach sequences and Salesloft cadences use different step models:

• Step types — Outreach supports automated email steps, manual email, call tasks, and generic action tasks. Salesloft uses email, phone, and "other" step types. Conditional and A/B-variant steps don't always carry over cleanly.
• Day/interval logic — Outreach uses interval days between steps; Salesloft uses a day-based cadence with explicit due dates. Re-timing every step manually is common.
• Branching and rulesets — Outreach Rulesets (auto-move prospects based on triggers) have no direct Salesloft equivalent. You'll rebuild that logic with Salesloft Automation Rules or accept a behavior change.
• A/B testing — Outreach's email-variant testing inside a sequence doesn't translate to a single Salesloft cadence structure.

Export your sequences, then rebuild them in Salesloft by hand or with a vendor migration script. Don't trust an automated copy to preserve timing or branching.

2. Data model and field mapping reset

Prospect, account, and activity objects differ between platforms. Custom fields you rely on for contact data segmentation won't auto-map.

Activity history is the usual casualty. Most teams archive historical Outreach activity reporting separately rather than migrating it, because the schema mismatch makes a clean import unreliable.

3. API and integration breaking changes

If you've built anything on the Outreach API, expect rework. The platforms use different REST structures, authentication scopes, and object names. A webhook listening for an Outreach prospect_stage_updated event has no equivalent payload in Salesloft.

Check the Salesloft developer docs against your current Outreach integrations and inventory:

1. CRM sync — Re-establish the Salesloft↔Salesforce or HubSpot connection. Field sync rules reset, so re-map every bidirectional field. If you're also weighing CRMs, see how HubSpot and Salesforce compare for B2B.
2. Webhooks — Rebuild every event listener against Salesloft event names.
3. Middleware — Zapier, Workato, or custom iPaaS flows referencing Outreach objects all break.
4. Dialer and recording — Call recording, local presence, and dialer integrations need reconnection and re-permissioning.

4. Snippets, templates, and content

Outreach snippets and templates don't import natively into Salesloft. Email templates, variables, and dynamic merge fields use different syntax. A merge token like {{first_name}} in Outreach may need reformatting for Salesloft's template engine. Audit every template for broken variables before sending live mail — a broken token in a 500-prospect cadence is a public mistake.

5. Permissions, teams, and admin structure

User roles, team hierarchies, and permission scopes are configured differently. Admins should:

• Recreate teams and group structures from scratch
• Re-assign cadence and content sharing permissions
• Verify governance settings (sending limits, compliance, opt-out handling)

Opt-out and unsubscribe lists are critical. Export your Outreach opt-out list and import it into Salesloft before the first send to stay compliant and protect domain reputation.

6. Reporting and analytics gaps

Dashboards reset. Metrics like sequence-step reply rates, prospect engagement scoring, and team activity rollups are computed differently. Historical trend data won't be continuous after cutover. Plan for a reporting blackout window and rebuild your key dashboards in Salesloft before reps need them for QBRs.

Migration checklist: order of operations

1. Audit every Outreach sequence, integration, custom field, and snippet.
2. Export prospects, accounts, opt-out lists, and templates.
3. Rebuild cadences in a Salesloft sandbox and test timing.
4. Re-map CRM field sync and rebuild webhooks/middleware.
5. Import opt-out lists first, then people and accounts.
6. Reformat template variables and snippets.
7. Recreate teams, roles, and permissions.
8. Rebuild dashboards and reports.
9. Pilot with one team before full cutover.
10. Cut over and monitor deliverability for two weeks.

This migration affects how SDRs run their day, so brief the team early — the same way you'd prep them for a sales discovery call. Behavior changes when the tool changes.

Key takeaways

• Sequence-to-cadence logic, branching, and A/B variants are the top breaking changes and need manual rebuild.
• API endpoints, object names, and webhooks differ — every custom integration breaks.
• Custom fields, activity history, snippets, and template variables don't auto-migrate.
• Import opt-out lists before any send to protect compliance and domain reputation.
• Run a sandbox pilot and accept a reporting blackout window before full cutover.
