Post-merger CRM consolidation case study: 4 platforms into 2 in 90 days

After a merger left two companies running two Salesforce orgs and two HubSpot portals, JayOh consolidated all four into one Salesforce and one HubSpot instance in 90 days. The work included 300+ hours of data cleansing and migration, rebuilt automations, new permissions and a re-validated HubSpot–Salesforce sync.

01 · Client type

Who was the client?

A merger creates one company on paper and two revenue systems in practice. Until the systems merge, nobody can report one pipeline, route one lead or pay one comp plan.

02 · Problem

What problem were they solving?

Problem 1

Four platforms, four versions of the truth

Two Salesforce orgs and two HubSpot portals each carried their own custom objects, lifecycle stages and field naming.

Problem 2

Duplicate and legacy data

Overlapping customers and prospects, incomplete records and years of legacy data had to be scrubbed before anything could merge cleanly.

Problem 3

Automations that collided

Process Builders, validation rules and HubSpot marketing and sales workflows from both sides overlapped or contradicted each other.

Problem 4

Ownership that no longer matched the org chart

Record ownership and permissions reflected the old companies, not the new business units and team responsibilities.

What system did JayOh build?

7 workstreams, in the order they matter. Each one closes a specific gap from the problem list above.

Stack
SalesforceHubSpot Marketing HubHubSpot Sales HubHubSpot–Salesforce connectorHubSpot CMSProcess BuilderValidation rules

Strategic roadmap and audit

Audited both Salesforce and HubSpot environments, mapped data, planned target architecture and built a phased roadmap to minimize disruption.

Standardized data models and fields

Harmonized custom objects, lifecycle stages, field naming conventions and key workflows across both platforms.

Automation consolidation

Audited and documented every Salesforce Process Builder, validation rule and HubSpot workflow, then consolidated or rebuilt them for the unified motion.

Data cleansing and migration

Scrubbed, transformed and migrated leads, contacts, deals and companies into one source of truth per system: 300+ hours of combined work.

Ownership, permissions and governance

New roles, permissions and user stories; record ownership reassigned to the new business units.

Unified integration

Configured the HubSpot–Salesforce sync (bidirectional field mapping, attribution, lead scoring) and reconnected and validated external integrations.

Website, domain and enablement

New HubSpot tracking, CMS and domain settings on both websites, embedded forms and conversion-tracking JavaScript; teams trained with SOPs and live workshops.

04 · Timeline

How long did it take? 90 days

The full consolidation was delivered in 90 days. Phases ran in this order; per-phase dates weren’t recorded in the case study.

Phase 1

Audit and roadmap

Both environments audited, data mapped, target architecture and phased plan agreed.

Phase 2

Harmonize

Objects, lifecycle stages, fields and automations standardized and rebuilt.

Phase 3

Migrate

300+ hours of cleansing, transformation and migration into one Salesforce and one HubSpot.

Phase 4

Integrate and launch

Sync, external integrations, websites and permissions validated; teams trained on SOPs.

06 · Takeaways

What made it work?

The operator lessons we’d apply to any team facing the same problem.

01

Harmonize definitions before moving data

Lifecycle stages, objects and field names were standardized first. Migrating before that just moves the conflict into one system.

02

Treat automation as migration scope

Every Process Builder, validation rule and workflow was audited. Inherited automations are where post-merger data silently breaks.

03

Re-permission for the new org chart

Ownership and permissions were rebuilt around the new business units, so routing and reporting reflected the company that actually exists.

Is this your situation?

Five signs we saw at this client before the work started. Tick the ones that are true for you; the more you tick, the closer your fix looks like this system.

Rule of thumb: 1–2 signs is a contained fix, 3 is this pattern, 4–5 means the system needs rebuilding rather than patching.

08 · FAQ

Questions about this case study

How long does a post-merger CRM consolidation take?
This one took 90 days to move four platforms (two Salesforce orgs, two HubSpot portals) into one Salesforce and one HubSpot. Timelines depend on record volume, custom objects and how many automations need rebuilding.
What was the hardest part of the merge?
Data and automation. Over 300 hours went into scrubbing, transforming and migrating duplicate, incomplete and legacy records, and every Salesforce Process Builder, validation rule and HubSpot workflow had to be audited and consolidated or rebuilt.
Should you keep both HubSpot and Salesforce after a merger?
This client did: one Salesforce for sales and one HubSpot for marketing, connected with a bidirectional sync. Whether you keep both depends on your motion; the rule is one instance of each system, not two of each.
How do you avoid disrupting sales during the consolidation?
A phased roadmap built from the initial audit, harmonized definitions before migration, reassigned ownership and permissions, and live workshops plus SOPs so reps knew the new process on day one.
Does JayOh handle the website and tracking side too?
Yes. In this engagement both websites got new HubSpot tracking scripts, CMS and domain configuration, embedded forms and custom JavaScript for conversion tracking.
