Data Migration : Tally, SAP B1 & Legacy Systems
Clean migration from Tally, SAP Business One, Salesforce, and legacy systems to Zoho or NetSuite. Data cleansing, field mapping, validation, reconciliation, and parallel-run support.
Your data is your business history, migration must be handled with precision.
Data migration is the most underestimated phase of any ERP or CRM project. Bad data in a new system is worse than no system at all. Aaxonix treats migration as a structured engineering project, not a bulk upload. We extract, cleanse, map, validate, and reconcile every record before sign-off.
For finance migrations, we run parallel systems until your team is confident the new system matches the old. Opening balances, historical transactions, customer and vendor ledgers, every number is verified before cutover. No shortcuts, no surprises.

Extract → Cleanse → Map → Validate, every record reconciled before sign-off
Both systems run simultaneously until your finance team confirms accuracy
How we handle your data migration.
Data Assessment
Full audit of your source system, data volume, quality, duplicates, missing fields, and format inconsistencies identified before migration begins.
Data Cleansing
Deduplication, format standardisation, missing value handling, and obsolete record archiving. Clean data goes into the new system.
Field Mapping
Source-to-target field mapping document reviewed and approved by your team. Every field, lookup, and relationship accounted for.
Trial Migration
Test migration in a sandbox environment. We validate record counts, field values, and relationships before touching production.
Validation & Reconciliation
Every migrated record reconciled against the source. Opening balances, transaction totals, and record counts verified.
Opening Balances
Customer/vendor ledgers, outstanding invoices, inventory quantities, and GL balances migrated with full reconciliation.
Parallel Run
For finance migrations: both systems run simultaneously for 2–4 weeks until your team signs off on accuracy.
Documentation
Migration mapping document, validation report, and reconciliation summary delivered for your records.
The Aaxonix method, six phases, no surprises.
Discovery & Requirements
Face-to-face process mapping. We learn your business before touching any configuration. We also confirm whether Zoho or NetSuite is the right fit, honest recommendation before any build begins.
Solution Architecture
Full design, data model, module stack, integration map, automation flows. You review and approve before any build begins. This phase is complimentary.
Build & Configure
Short sprints, weekly demos. You see progress every week, not a big reveal at go-live full of surprises.
Testing & UAT
Structured testing against your original requirements. We don't go live until your team has signed off on every scenario.
Go-Live & Hypercare
Controlled go-live with a 2–4 week hypercare period, dedicated support to catch every edge case before it becomes a problem.
Training & Handover
Role-based training and full admin documentation. Our definition of done: your team runs the system completely independently.

Frequently asked about Data migration.
We migrate from Tally ERP/Tally Prime, SAP Business One, Salesforce, Microsoft Dynamics, legacy spreadsheets, and custom databases. Any system that can export data in CSV, Excel, or via API can be migrated.
We run a four-step process: data extraction, cleansing (deduplication, format standardisation), mapping to the target schema, and validation. Every migrated record is reconciled against the source before sign-off.
Yes. We migrate opening balances, historical transactions, customer/vendor ledgers, and outstanding invoices. The depth of history depends on your reporting needs, we advise on what’s worth migrating vs. archiving.
For finance migrations, we always recommend a parallel-run period where both old and new systems operate simultaneously. This lets your team verify that the new system produces the same outputs before cutting over.
Simple migrations (contacts, products) take 1–2 weeks. Full financial migrations with historical data, opening balances, and parallel runs typically take 3–6 weeks. Complex multi-entity migrations may take 6–10 weeks.
