Duplicates and inconsistent records
Multiple sources often contain conflicting names, identifiers, statuses and contact details that create unreliable customer views.
Move legacy CRM, spreadsheet and enterprise data into Salesforce with relationships, history and business meaning intact. IDS Logic plans, cleanses, rehearses and reconciles every migration around measurable acceptance criteria.


Protect the Foundation of Salesforce
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.
Multiple sources often contain conflicting names, identifiers, statuses and contact details that create unreliable customer views.
Accounts, contacts, opportunities, cases, activities and files must be loaded in the right order with traceable source identifiers.
Incorrect mappings, owners, picklists or dates can trigger the wrong process and make dashboards disagree with source systems.
Without rehearsals, delta planning and exception ownership, the final load becomes an avoidable risk to operations and adoption.
End-to-End Migration Control
Our data engineers, Salesforce specialists, analysts and testers work as one team so business definitions, technical loading and acceptance evidence remain connected.
Build a fact-based view of source systems, record volumes, quality, relationships and migration constraints.
Decide what should move, what should be transformed, what should be archived and when each dataset is required.
Correct inconsistent formats, incomplete values and obsolete records before they undermine Salesforce processes.
Resolve duplicate organisations, people and business records using transparent, reviewable matching rules.
Translate legacy structures into a Salesforce model that supports processes, security, automation and reporting.
Move data from third-party CRMs, databases, ERP platforms, bespoke applications and structured files.
Combine business units, acquired organisations or existing Salesforce orgs without losing ownership and history.
Preserve the context users need while avoiding unnecessary volume and inaccessible legacy information.
Plan efficient extraction and loading for high-volume objects while protecting business-critical operations.
Protect sensitive migration data and align technical handling with agreed governance and retention decisions.
Prove the migration repeatedly before go-live using measurable acceptance criteria and exception handling.
Coordinate final extraction, delta loads, go-live validation and the transition into stable business operation.
Relationship-Aware Migration
The load itself is only one stage. Scope, quality, model, sequencing and evidence determine whether the migrated data supports real work.
Systems, extracts, identifiers, owners, volumes and technical access.
Records, history, files, retention, archives and migration phases.
Completeness, duplicates, formats, conflicts and approved corrections.
Objects, fields, owners, relationships, picklists and external IDs.
Dependency order, transformations, batches, exceptions and delta data.
Counts, control totals, reports, user validation and signed acceptance.
Flexible Migration Engagements
Start with an evidence-led assessment, commission end-to-end delivery or add specialist migration capacity to an existing Salesforce programme.
Profile representative source data and define the complexity, risks, decisions and effort required for a credible migration plan.
IDS Logic owns profiling, cleansing, mapping, load cycles, reconciliation, cutover and post-go-live data support.
Data engineers, analysts, testers and Salesforce specialists work alongside your implementation partner or internal team.
Evidence Before Cutover
We agree objective entry and exit criteria so issues are resolved during rehearsals rather than discovered by users after launch.
Scope, ownership, access, retention and quality risks are understood.
Transformation, matching, defaulting and relationship rules are signed off.
Full-volume loads meet technical, reconciliation and business criteria.
Delta plan, freeze, rollback, communications and hypercare ownership are confirmed.
Traceable Source-to-Target Delivery
We retain traceability between source identifiers, transformation rules, load results and target records so migration decisions can be explained and validated.
Migration Coverage
We shape the migration around business continuity, target architecture and future data ownership—not simply the shortest route to importing records.

Migration Evidence & Control
Migration reporting should make quality and readiness visible to business, technical and governance stakeholders throughout the programme.
Why IDS Logic
We can own the data workstream independently or integrate it with Salesforce consulting, implementation, custom development and managed support.
Mappings and cleansing rules are validated with data owners so technically valid records remain useful to the organisation.
Salesforce specialists, data engineers, analysts, testers and integration developers address the whole migration problem.
Source IDs, mapping rules, load results and exceptions remain traceable across rehearsal and production cycles.
We distinguish one-time historical movement from ongoing synchronisation and design ownership accordingly.
Technical counts, business reports, relationship checks and user validation create a shared definition of done.

Relevant Data, Migration & Integration Experience
The projects below demonstrate relevant experience across platform migration, enterprise data flows and system integration. While not all are Salesforce data migration engagements, each reflects the delivery expertise required to preserve operational context, manage dependencies and maintain continuity across connected systems.
A controlled migration from Laravel to WordPress increased content ownership while maintaining reliable Salesforce integration and alignment with ICA's wider portal ecosystem.
A modern Umbraco commerce platform was delivered alongside a significant Dynamics 365 ERP migration and high-volume ordering requirements.
Connected Microsoft workflows improved information control, reduced manual handling and created a more dependable operational process.
Hessington Health is a national health screening and occupational health service provider. We have been scaling up our business activity aggressively over the past 12 months and our workflow/IT needs have changed significantly as we have grown. We instructed IDSLogic for their passion to support business in helping them to create efficient processes, which in the long term save time and money. Thery have start with getting a very granular understanding of the clients needs and then offer several solutions. They have helped us integrate Power Automate processes in our SharePoint system. They date flow works flawlessly within SharePoint which helps achieve grater data security, and process management. We have now instructed them to develop our Patient App. I can not recommend them enough.

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