Data Safety

How We Protect Data Integrity

Every migration decision we make is designed around one principle: no data is ever lost, corrupted, or exposed.

Full Backup Before Anything

Before a single script runs, we take a complete backup of your source store — database, media files, and configuration. You can always go back.

Automated Validation Passes

After every migration run, automated scripts check record counts, attribute completeness, relationship integrity, and data types across all migrated entities.

Delta Sync at Go-Live

Your live store keeps running during migration. At go-live, we run a delta sync to capture all changes made since the initial migration — no data left behind.

Secure Data Handling

All data is transferred over encrypted connections. Customer passwords are migrated as hashes — never in plaintext. GDPR compliance maintained throughout.

Precision Engineering

Data Mapping & Migration Validation

We do not copy-paste data. We engineer the migration — field by field, with validation at every step.

1

Source Audit

We export and analyse the full schema of your source platform — tables, relationships, custom attributes, and data volumes. Nothing is assumed; everything is documented.

2

Target Schema Design

We map every source field to its destination equivalent on the new platform. Where there is no direct equivalent, we design the target structure before any data moves.

3

Transformation Rules

Data rarely migrates 1:1. We define transformation rules for format changes, value normalisations, relationship restructuring, and any enrichment needed.

4

Test Migration Run

We run a full migration on a staging environment and validate every entity type — comparing source and destination counts, spot-checking records, and flagging anomalies.

5

Sign-Off Validation

Your team validates the staging data against the live store. Any discrepancies are documented, root-caused, and resolved before final go-live approval.

6

Production Migration

Final migration runs against production data, followed by automated validation scripts. Delta sync applied, counts verified, and go-live confirmed only when all checks pass.

Step by Step

Our Data Migration Process

A structured, repeatable process refined across hundreds of migrations — no improvisation, no surprises.

1

Discovery & Data Audit

3–5 days

We assess your source platform schema, data volumes, custom attributes, and any known data quality issues. You receive a detailed migration plan and timeline.

2

Environment & Tooling Setup

2–3 days

Target environment configured, migration scripts initialised, and staging environment prepared for the first test run.

3

Data Mapping & Transformation Design

3–7 days

Every entity type mapped from source to destination. Transformation rules written and reviewed. Edge cases documented before any data moves.

4

Initial Migration Run

1–5 days

Full migration executed on staging. Automated validation scripts run immediately after. Record counts, relationships, and attribute data verified.

5

UAT & Stakeholder Validation

3–5 days

Your team reviews key data sets on staging — products, customers, orders. Any issues raised are fixed and the migration re-run until sign-off is given.

6

Delta Sync & Go-Live Migration

Launch day

Final migration of production data, delta sync to capture recent changes, automated validation, and confirmation before DNS switch.

7

Post-Migration Verification

1–2 days

Post-launch verification of live data against source. Any discrepancies investigated and resolved within the stabilisation window.

Edge Cases Handled

Handling Complex & Custom Data

Standard migration tools handle standard data. When your store has complexity, you need an engineering team — not a script.

Custom Attributes & Entity Types

Non-standard product attributes, custom entity types, and proprietary data structures are reverse-engineered and mapped to equivalent or new structures on the target platform.

Legacy & Corrupted Data

Old stores often have data quality issues — orphaned records, inconsistent formats, or null values in required fields. We identify, clean, and normalise data before migration.

ERP-Synced Data

When your store data is mastered in an ERP (SAP, Dynamics, NetSuite), we coordinate migration with your ERP team and establish the post-migration sync strategy from day one.

Multi-Store & Multi-Locale Data

Multi-language content, multi-currency pricing, and per-store configurations are migrated with scope intact — no flattening, no loss of locale-specific data.

Large Volume Catalogs

Stores with 100K+ SKUs require chunked migration strategies, optimised batch sizes, and careful index management. We have done this at scale — without timeouts or memory failures.

Custom Pricing & B2B Data

Tier prices, customer group pricing, contract-based price lists, quote history, and company account hierarchies are all migrated with full relational integrity.

Risk Mitigation

Risk Reduction & Business Continuity

Every risk we have encountered across hundreds of migrations is now part of our standard process. Here is how we handle the most common ones.

RISK

Data loss during migration

Full source backup before any work. Automated post-migration record count validation. Rollback plan documented and tested.

RISK

Store downtime during the migration window

All migration work happens on staging. Live store stays operational. Delta sync captures changes. Go-live window under 30 minutes.

RISK

Customer login disruption after migration

Passwords migrated as hashed values — customers log in without resetting. Account history and addresses visible from day one.

RISK

Order history unavailable post-migration

Full order history including invoices, shipments, credit memos, and payment records migrated and verified before sign-off.

RISK

Data quality issues surfacing post-launch

Pre-migration data quality audit identifies issues before they become problems. Cleansing and normalisation completed on source data first.

RISK

GDPR or compliance exposure during transfer

All data transfers over encrypted connections. Passwords remain hashed. No PII stored in plain text at any stage of the process.

FAQ

Data Migration Questions, Answered

Straight answers to the questions we hear most.

Will any data be lost during the migration?
No. We take a full backup before any work begins, run automated validation after every migration pass, and only confirm go-live when all record counts and integrity checks pass. Zero data loss is our standard, not an aspiration.
Can customers still log in after the migration?
Yes. Customer passwords are migrated as hashed values — the same hash format is retained on the new platform so customers can log in without resetting their passwords.
How long does a data migration take?
The data migration phase itself typically takes 1–2 weeks for standard stores. Larger catalogs, complex custom data, or extensive data quality issues can extend this. We give you a fixed timeline after the discovery audit.
What happens to data created in the live store during migration?
We use a delta sync strategy. After the initial migration, the live store keeps running normally. At go-live, we run a final delta sync to capture all new orders, customers, and changes made since the initial migration.
Can you migrate data from a custom-built platform?
Yes. Custom platforms require reverse-engineering the data schema, but this is something we do regularly. The audit phase is longer, but the migration outcome is the same — complete and validated.
What about data quality issues in our current store?
We run a data quality audit before migration. Orphaned records, inconsistent formats, null required fields, and duplicate entries are identified and either cleaned before migration or flagged for your review.
Is the migration GDPR compliant?
Yes. All data is transferred over encrypted connections. Customer passwords remain hashed at all times. No personally identifiable information is stored in plaintext during the migration process.
