Find the 20% of issues causing 80% of the risk
Issues are grouped by object and cause, so a handful of duplicate suppliers or missing tax codes are fixed once instead of record by record.
A new ERP with old data is still the old ERP. Data Semantics cleans, maps and reconciles your data before cutover, up to 4–5× faster than a manual migration, at around half the cost, with opening balances within 0.5% and every rule on record.

Oracle Fusion · D365SAP S/4HANATemenos T24OPERA Cloud · SalesforceData Semantics migrates master and transactional data between ERP, CRM, core banking and industry platforms, end to end or alongside your implementation partner. In DataPrep 360, AI profiles the data, surfaces hidden business rules, suggests mappings, writes and fixes the transformation code, and reconciles source to target after every test load. Business owners approve every rule, and every decision is recorded.
Most migrations copy the data across, dirt and all, leave the business rules undocumented and lose the history. A system change is the one moment you can clean your data, record what it means and make it usable by AI from day one. Migrations still run on spreadsheets and hand-written scripts, so test cycles take weeks and reconciliation happens when there is no time left.
A data quality phase, typically 4 to 6 weeks, profiles every source for duplicates, gaps and broken references. Instead of a list of thousands of errors, business owners get a ranked plan and fix the few that matter first, with our team supporting every correction.
Issues are grouped by object and cause, so a handful of duplicate suppliers or missing tax codes are fixed once instead of record by record.
An Eisenhower matrix separates what blocks the next test load from what can be cleaned in parallel, so the program never waits on data.
AI takes on the slow, repetitive work of a migration, so test cycles take days, not weeks. Our migration specialists review every output and your business owners approve every rule. Mapping, code generation and data quality checks run in DataPrep 360, our migration workspace; the other steps are run by our specialists with AI-assisted tooling, and every result is recorded there.
AI scans every source table for gaps, duplicates and broken values before anyone plans a load.
You get: a readiness view per data object
Checked by: specialists, with your data owners
AI reads legacy code, configuration and reports and proposes the business rules they contain, with where each one was found.

Migrations rarely come alone. A new ERP or core banking platform usually brings a CRM change, a history decision and new reporting. We handle them together, so the same rules, mappings and decisions carry through.
ERP Data Migration moves charts of accounts, customers, suppliers, items, open items and balances from one ERP to another.
Core Banking Data Migration maps and moves customers, accounts, contracts, limits and balances between core banking platforms, where data models are deep and every number is regulated.
CRM Migration & Consolidation moves or merges customer, account and pipeline data across CRMs and Salesforce orgs into one trusted set of records.
Industry & Line-of-Business Platforms migrates specialist systems that carry the operating detail of your industry, alongside the ERP and CRM they feed.
Merger & Entity Consolidation brings two organizations' finance, customer and supplier data onto one set of systems after a merger or restructure.
Historical Data & Archival keeps the history you need reachable without loading all of it into the new system, and lets you switch the old one off.

A migration decision record is the written history of each business rule: what the old system did, what the new one will do, who decided and why. It sits next to every AI suggestion, mapping and reconciliation, so any difference at cutover resolves to one of two things: a defect to fix, or a change someone approved on purpose.
AI surfaces the logic in the old system as candidate rules, each with where it came from and how confident it is, before anyone writes a mapping.
Finance decides finance rules, operations decides product rules. Each decision is reviewed in plain language, not code, and recorded with its reason.
When old and new don't match, the record shows whether it's a defect or an approved change. Steering committees stop debating and start signing off.
Audit, regulators, finance and leadership can see the rules, decisions and reconciliations at any point, not just in a pack assembled the week before cutover.
An ontology is a shared model of your business: customers, accounts, contracts, suppliers and the rules between them, mapped to the systems where each lives. Every mapping and rule decision in a migration defines part of that model. We keep it, so the work you pay for once keeps paying back in analytics and AI.
Many teams plan to migrate in-house or through their implementation partner. That can work. Our AI-assisted method fits around it, so you pay for what cuts time and risk, not for work already covered.
We add AI rule discovery, mapping assistance, decision records and independent reconciliation to the migration your in-house team or implementation partner is running.
Profiling, mapping, code, test loads, reconciliation, cutover and archival, delivered by our team, with your business owners making the decisions.
Most programs believe they are closer to cutover than they are. A fixed-price Migration Readiness Check shows the real picture. Projects then run from 6 weeks, aligned to your implementation program, and are priced as a fixed bid on the number of data objects.
Fixed price. We profile one source system, surface its hidden rules and show where your migration really stands.
Take one object, such as customers or accounts, through AI mapping, code, load and reconciliation.
Run the full migration with us, or add our AI and reconciliation to the one already under way.
Carry the quality rules into production, archive the history and feed analytics.
About migration
Application data migration moves the data a business application runs on, such as an ERP, CRM or core banking system, so the business can operate on the new system. Data platform modernization moves analytical warehouses, pipelines and reports to Microsoft Fabric, Databricks or Snowflake. Data Semantics often runs both together, so history from the old application lands on the new data platform.
In Data Semantics programs, AI-assisted migration runs up to 4 to 5 times faster than a manual migration, at around half the cost. AI profiles the source data, surfaces hidden business rules, suggests source-to-target mappings, writes the transformation and load code, fixes failed test loads and runs reconciliations. That removes most of the manual spreadsheet and scripting work, so each test cycle takes days instead of weeks.
Yes, because nothing goes live on AI judgement alone. Every mapping and rule is approved by a named business or technical owner, every code change is tested, and every decision is kept in a decision record that audit can review.
Migration routes
Common routes include Oracle EBS to Oracle Fusion or Dynamics 365, Dynamics AX to Dynamics 365, SAP ECC to SAP S/4HANA, legacy ERPs such as JD Edwards or Sun to NetSuite or Dynamics 365, iMAL, Finacle or FLEXCUBE to Temenos T24 or a new core, Salesforce org merges, Dynamics CRM to Salesforce or the reverse, and OPERA 5 to OPERA Cloud. Other ERPs, CRMs, industry platforms such as Yardi and LS Retail, and homegrown systems are covered on request.
Quality and control
With a data quality phase, typically 4 to 6 weeks, before the first full test load. Data Semantics profiles every source for duplicates, gaps and broken references, ranks issues with Pareto charts and an urgent-versus-important (Eisenhower) matrix, and supports business owners as they fix the few issues that matter most first.
Data Semantics targets opening-balance variance within 0.5% at cutover, and every remaining difference is either fixed as a defect or explained by a recorded, approved decision before sign-off.
Yes. Every mapping, rule decision, test load and reconciliation is recorded, so auditors, regulators and finance can see the evidence at any point, not only in a pack assembled the week before cutover. Each business rule has a migration decision record: what the old system did, what the new one will do, who decided and why, so every difference found at reconciliation traces to either a defect to fix or a change made on purpose. For banks, the evidence is prepared for regulatory review.
Closed history that does not need to move into the new application is archived to your data platform, such as Microsoft Fabric, with its keys and lineage preserved, so it stays reportable and the old system can be retired.
Working together
Yes. With migration assurance, your team or partner runs the program while our engineers, with AI-assisted tooling, provide rule discovery, mapping assistance, decision records and independent reconciliation. Or we run the migration end to end.
Time and cost
Data Semantics projects run from 6 weeks for a focused migration, longer for larger programs, because the plan is aligned to your implementation program, its test cycles and its cutover. The data quality phase on its own typically takes 4 to 6 weeks. Pricing is a fixed bid based on the number of data objects in scope, such as customers, suppliers, items, accounts, open balances and history. It starts with a fixed-price Migration Readiness Check, so you know the cost before the work starts.
Bring us one source system, whether ERP, CRM or core banking. We’ll profile the data, surface the hidden rules and show you where you stand, before cutover makes the decision for you.
