Protect the Foundation of Salesforce

A migration can complete technically and still leave users with data they cannot trust

Data quality, relationships, history and ownership determine whether automation, reporting and customer service work after go-live. We make those conditions explicit before records are moved.

Duplicates and inconsistent records

Multiple sources often contain conflicting names, identifiers, statuses and contact details that create unreliable customer views.

Broken relationships and history

Accounts, contacts, opportunities, cases, activities and files must be loaded in the right order with traceable source identifiers.

Automation and reporting failures

Incorrect mappings, owners, picklists or dates can trigger the wrong process and make dashboards disagree with source systems.

Cutover disruption

Without rehearsals, delta planning and exception ownership, the final load becomes an avoidable risk to operations and adoption.

End-to-End Migration Control

Salesforce data migration services from source assessment to reconciled go-live

Our data engineers, Salesforce specialists, analysts and testers work as one team so business definitions, technical loading and acceptance evidence remain connected.

Relationship-Aware Migration

Six connected controls turn raw source records into usable Salesforce data

The load itself is only one stage. Scope, quality, model, sequencing and evidence determine whether the migrated data supports real work.

01

Sources

Systems, extracts, identifiers, owners, volumes and technical access.

02

Scope

Records, history, files, retention, archives and migration phases.

03

Quality

Completeness, duplicates, formats, conflicts and approved corrections.

04

Model

Objects, fields, owners, relationships, picklists and external IDs.

05

Load

Dependency order, transformations, batches, exceptions and delta data.

06

Proof

Counts, control totals, reports, user validation and signed acceptance.

Flexible Migration Engagements

Choose the level of migration ownership your programme needs

Start with an evidence-led assessment, commission end-to-end delivery or add specialist migration capacity to an existing Salesforce programme.

Frequently Asked Questions

Salesforce data migration questions, answered

For advice based on your source systems, data quality, volumes, relationships and go-live constraints, speak directly with our Salesforce migration team.

What is included in Salesforce data migration services?

Salesforce data migration can include source-system discovery, data profiling, scope and retention decisions, cleansing, de-duplication, field and object mapping, transformation rules, relationship preservation, test loads, reconciliation, cutover planning and post-migration support. The exact scope depends on the number of sources, data quality, record volumes, historical content, integrations and the target Salesforce data model.

What data can IDS Logic migrate into Salesforce?

We can migrate accounts, contacts, leads, opportunities, cases, products, price books, campaigns, activities, notes, files, attachments, users, custom objects and other business records where the target model and permissions allow. We can also consolidate data from several CRMs, databases, spreadsheets and operational systems into one Salesforce environment.

Can you migrate data from a legacy CRM or bespoke system?

Yes. IDS Logic can extract and transform data from legacy CRMs, bespoke databases, spreadsheets, ERP applications and other line-of-business systems. Discovery includes source structures, identifiers, relationships, data ownership, export methods and any limitations that may affect completeness or migration order.

Do you provide Salesforce org-to-org migration and consolidation?

Yes. We can support Salesforce-to-Salesforce migration, business-unit consolidation, sandbox-to-production data movement and the controlled merger of multiple orgs. The plan considers object models, record ownership, external IDs, duplicate strategy, automation, integrations, files, activities and reporting requirements.

How do you cleanse and de-duplicate data before migration?

We profile source data to identify duplicates, incomplete records, inconsistent formats, invalid values and conflicting definitions. Cleansing rules are agreed with data owners before execution. Matching can use business identifiers, external IDs and carefully defined rules, with exceptions reviewed rather than automatically merged when confidence is insufficient.

How do you preserve relationships and historical records?

Migration order is planned around object dependencies and record relationships. We use stable source identifiers and external-ID strategies where appropriate, then validate parent-child links, ownership, activities and historical records after each load. Some legacy content may require an archive or read-only access approach rather than direct migration.

How do you validate that a Salesforce migration is accurate?

Validation combines automated record counts, control totals, relationship checks, exception logs, duplicate checks, field-level comparisons, business reports, user acceptance and targeted spot checks. Reconciliation evidence is agreed before cutover so stakeholders know what constitutes a successful migration and which exceptions remain.

Can you minimise downtime during Salesforce data migration?

Yes. We use rehearsal loads, staged extraction, delta planning and a controlled cutover sequence to reduce interruption. The achievable downtime depends on source-system export options, data volume, business transaction rates, target automation and whether users can continue changing records during the final migration window.

How do you address security and UK GDPR during migration?

We apply least-privilege access, secure transfer and storage, controlled environments, documented handling procedures and removal of temporary migration data when it is no longer required. Data minimisation, retention, lawful-basis and compliance decisions remain with your organisation and advisers; IDS Logic provides technical controls and evidence to support those decisions.

How long does a Salesforce data migration take and what does it cost?

A focused migration from one clean source may take several weeks, while a multi-system programme with poor data quality, complex relationships, files and several rehearsal cycles can take several months. Cost depends on source count, volume, complexity, cleansing effort, target design, testing, cutover constraints and post-go-live support. We assess these factors before proposing a transparent scope.
