DataLift™ and the Truth About Migration: Clean Data, Clean Close

ERP success lives or dies on data. If master records are inconsistent, transactions are incomplete, and historical balances don’t reconcile, confidence evaporates—even when the system “works.” DataLift™, a core accelerator in Dawgen ERPath™, converts data migration from a late-stage scramble into a governed, phased, auditable program that protects the clean core and delivers a clean financial close on day one. This article explains the practical truths of data migration, why most programs underestimate it, and how to run DataLift™ across the ERPath™ phases to ensure accuracy, traceability, and trust.

1) Why Data Breaks ERP (And How to Prevent It)

Root causes:

• Late attention: migration is postponed until configuration stabilizes; quality debt accumulates.

• Ambiguous ownership: master data ownership and stewardship are unclear; fixes are “IT’s job.”

• One-shot loads: a single, heroic cutover attempt with minimal rehearsals.

• Missing evidence: balances don’t tie to the GL; auditors lack a trail; business loses confidence.

DataLift™ countermeasures: early profiling, role-clear ownership, wave-based strategy, rehearsal cutovers, and a reconciliation-first mindset with auditable evidence.

2) The DataLift™ Method at a Glance

Principles:

1. Start early; iterate often. Profiling begins in Discover, with remediation running in parallel to design/config.

2. Waves, not waterfalls. Separate Master → Open Transactions → Historical to reduce risk and speed feedback.

3. Evidence beats opinion. Reconciliations to sub-ledgers and GL determine “done,” not subjective sign-off.

4. Keep the core clean. Fix data at the source; avoid custom transformations that mask defects.

5. Protect privacy & integrity. Mask sensitive data in non-prod; enforce referential integrity across loads.

6. Own the domains. Business Data Owners decide the standards; IT enables the pipeline.

Outputs: DQ scorecards, mapping specs, transformation rules, migration runbooks, reconciliation workbooks, and an auditable data pack for go-live.

3) Aligning DataLift™ to ERPath™ Phases

Phase 0 – Mobilize

• Identify critical domains (customers, vendors, items, chart of accounts, banks, employees).

• Nominate Data Owners & Stewards; establish the Data Governance Council.

• Draft the Data Quality (DQ) charter and initial risk register.

Phase 1 – Discover

• Run profiling: duplicates, completeness, validity, uniqueness, referential integrity.

• Produce DQ scorecards and remediation backlog prioritized by value/risk.

• Inventory sources (ERP, WMS, CRM, spreadsheets); decide single source of truth per attribute.

• Begin mapping catalogs (source → target → business rule → steward).

Phase 2 – Architect

• Finalize target model & code sets (UoM, tax codes, currency, payment terms).

• Define transformation rules (e.g., address parsing, SKU harmonization).

• Select load mechanisms (APIs, staging tables, import templates).

• Approve reconciliation logic: sub-ledger tie-outs, trial balance checks, aging alignment.

• Approve masking strategy for non-prod.

Phase 3 – Configure

• Build repeatable pipelines with error logging and idempotency.

• Execute Wave 1 (Master) dry-runs into non-prod; iterate mapping and cleansing.

• Prepare test data packs for SIT/UAT seeded from masked real data.

Phase 4 – Validate

• Rehearse Wave 2 (Open Transactions) and Wave 3 (Historical); run full reconciliations.

• Capture audit evidence: before/after counts, exception logs, tie-out workbooks.

• Perform performance & volume tests on loads; confirm cutover window.

Phase 5 – Deploy

• Execute cutover per runbook: sequencing, checkpoints, rollback criteria.

• Run Day-1/Day-3 reconciliations; publish confidence report to SteerCo.

Phase 6 – Realize

• Final historical backload (if staged); activate MDM operating model; transition to BAU stewardship.

4) The Three Waves—Depth Guide

4.1 Wave 1: Master Data

Scope: customers, vendors, items/products, BoMs, locations, chart of accounts, cost centers, banks, employees, tax codes.
Quality gates:

• Uniqueness (no duplicates); validity (mandatory attributes present); reference alignment (UoM, currency, terms).

• Address normalization; contact method standardization; bank IBAN/SWIFT validation where applicable.
  Remediation patterns: merge rules for duplicates; survivorship logic (authoritative source per attribute); code conversion tables.
  Owner actions: approve standards; sign off DQ thresholds; assign stewards.

4.2 Wave 2: Open Transactions

Scope: open AR/AP, open POs, open production orders, open service orders, on-hand inventory by lot/serial/location, WIP balances.
Quality gates: cutoff date alignment; status normalization; price/cost validation; on-hand vs GL reconciliation; location accuracy.
Reconciliations:

• AR/AP aging to sub-ledgers + GL control accounts.

• Inventory sub-ledger to GL; WIP roll-forward.

• Bank balances to GL (pre-cutoff); petty cash confirmation.

4.3 Wave 3: Historical

Scope: closed invoices, posted receipts/issues, GL history (trial balance), historical BOM revisions, sales history for planning/analytics.
Approach options:

• Summary balances (e.g., opening TB per period) for speed, plus detailed history in the data lake.

• Selective detail: keep line-level history for revenue recognition, warranty, quality analysis.
  Reconciliations: TB match; revenue/cost alignment by period; tax/GCT/VAT audit trail sufficiency.

5) Data Quality (DQ) in Practice

Profiling metrics: completeness %, uniqueness %, domain validity %, referential integrity %, outlier counts.
Scorecards: visual heatmaps by domain and attribute; thresholds trigger remediation sprints.
Cleansing techniques: standardization, enrichment (postcode/geo), deduplication (fuzzy/phonetic), survivorship.
Golden records: MDM establishes the authoritative record with stewardship workflow.
Change controls: prevent regression by gating interface loads and enforcing validation in the ERP.
People matters: incentives for frontline data capture; training on why each field matters.

6) Reconciliation: The Non-Negotiable

Financial tie-outs:

• Sub-ledger totals (AR/AP/Inventory) = GL control accounts.

• TB before/after balance equality at cutover.

• Aging reports match open items migrated.

Operational tie-outs:

• On-hand inventory quantities match physical counts (cycle counts where full counts aren’t feasible).

• Production/WIP balances roll-forward correctly.

Evidence pack: signed workbooks, screenshots, query extracts, and exception logs retained for audit.

7) Integration & Data at the Edge

IntegrationHub™ patterns stabilize the perimeter:

• API vs Batch: choose by latency/volume/transaction integrity.

• Idempotency: re-load without duplication; checkpointing.

• Observability: message tracing, error queues, replay procedures.

• Data contracts: versioned schemas; backward-compatible changes to avoid breakage.

8) Environments, Privacy & Non-Prod Hygiene

• Masking: anonymize PII/sensitive fields; scramble financial amounts where appropriate.

• Subsetting: create smaller but relationally intact datasets for faster tests.

• Refresh cadence: automated non-prod refreshes with re-masking and integrity checks.

9) Governance & Roles

• Data Governance Council: approves standards, thresholds, and exceptions.

• Data Owners (business): accountable for domain quality and sign-offs.

• Stewards: hands-on remediation, monitoring, and change requests.

• Migration Lead/Team: pipeline build, loads, logs, reconciliations, evidence pack.

• Audit/Compliance: reviews evidence, segregation of duties in tooling, and privacy compliance.

10) Tooling & Templates (DataLift™ Pack)

• Mapping Catalog (source → target → rule → owner).

• DQ Scorecards (by domain/attribute).

• Transformation Rules with examples and test cases.

• Load Runbooks (step-by-step, with checkpoints and rollback).

• Reconciliation Workbooks (AR/AP/Inventory/GL).

• Masking Specs + non-prod refresh scripts.

11) Case Vignettes (Illustrative)

11.1 Consumer Goods Importer

Problem: three item lists, conflicting UoM; negative inventory on go-live rehearsal.
Fix: harmonized UoM, survivorship rules, Wave-2 rehearsal; inventory → GL reconciliation.
Result: go-live with 99.6% item/location accuracy; close cycle −5 days.

11.2 Regional Manufacturer

Problem: duplicate customers; AR aging misaligned with GL.
Fix: fuzzy dedupe + consolidation; AR open items re-aging; GL control tie-out.
Result: DSO −7 days; audit findings closed on first attempt.

11.3 Distributor

Problem: historical price list chaos; margin analytics unreliable.
Fix: historical backload by summary TB + detailed sales lines to data lake; standardized price lists.
Result: pricing discipline restored; forecast accuracy +9 p.p.

12) Pitfalls to Avoid

1. Treating migration as an IT task. Make Data Owners accountable.

2. Over-loading Wave 3. Only load detail that has a clear business or compliance use.

3. Skipping rehearsal. Dress rehearsals de-risk timing, volumes, and defects.

4. Custom transforms to “fix” bad data. Fix at source; document rule intent when transform is unavoidable.

5. No masking in non-prod. Privacy incidents in test are still privacy incidents.

13) Frequently Asked Questions

Q: How much history should we bring?
A: Enough to satisfy statutory/audit needs and analytics. Use summary TB for speed; keep detailed history in the lake.

Q: Who signs off on data quality?
A: Data Owners in the business, based on DQ thresholds and reconciliation results—advised by stewards and the migration team.

Q: Can we load everything at once?
A: Technically yes; practically risky. DataLift™ favors waves with rehearsals to isolate issues and prove evidence.

Q: What about multi-currency and FX?
A: Normalize to base currency for reconciliation; store source currency and FX rate; verify historical revaluation logic.
