Expert Odoo implementation in Chennai for version moves

Chennai accounts teams are careful, and they will not sign off a new system until the trial balance matches the auditor's file to the last rupee. That standard shapes how we migrate. A company in Guindy on Odoo 12, or a group on OMR still running an older ERP beside Tally, needs open invoices, stock values, advances and GST credits carried across without gaps. We map every field, script the move, run it twice on a copy and compare reports side by side with your finance head. Offices in Ambattur and teams in Kanchipuram follow the same tested plan.

Migration work our Odoo specialists handle

From old versions, old systems and old spreadsheets

Odoo version jumps

Moves from Odoo 11, 12 or 14 to Odoo 17 or 18, with custom modules ported and retested rather than copied blindly.

Legacy ERP exits

Masters, balances and open documents pulled from an older ERP, cleaned and loaded with a field-by-field mapping sheet.

Tally ledger moves

Ledgers, groups, cost centres and bills outstanding moved from Tally so Odoo opens with the same figures.

Duplicate data cleanup

Customers, vendors and products de-duplicated before loading, so reports in Odoo start clean from day one.

Custom module porting

Old Python code rewritten for the new ORM and OWL front end, dropping modules the new version no longer needs.

Parallel run

One period run in both systems with daily comparisons, so differences are found while the old system is still live.

Tamil Nadu GST rebuild

GSTINs, e-invoice IRN for turnover above Rs 5 crore and e-way bills over Rs 1 lakh set up and tested again.

Auditor sign-off pack

Opening balance reports, mapping sheets and reconciliation notes bundled for your auditor to check in one sitting.

Rollback plan

A written fallback for the cutover weekend, so the business knows exactly what happens if a check fails.

Why Chennai finance heads trust our migrations

A migration fails quietly: balances that drift, documents that never arrived, reports that disagree by a small amount nobody can explain. Symake's senior consultants have run migrations across 200+ projects and treat reconciliation as the deliverable, not an afterthought. Every load is scripted so it can be rerun, every count is checked against the source, and your finance team approves each comparison before cutover is scheduled.

Six steps to a clean version move

Each one ends with a check your finance team signs

Inventory

We list every module, report, integration and data table the current system holds.

Map

Old fields are matched to new ones in a mapping sheet your process owners approve.

Script

Migration scripts are written, versioned and run on a copy of your Chennai database.

Rehearse

Two full trial runs, each followed by a balance and record-count comparison.

Cut over

The live move happens over a planned weekend with our consultants on call throughout.

Settle

Close support for the first month, with daily checks until the books close cleanly.

Expert help shaped for Chennai

Companies in Chennai rarely start fresh. They arrive with years of history that must come across intact. Our senior team has moved data for clients in manufacturing, FMCG, real estate, education, healthcare, distribution and logistics, retail and hotels, and the method stays the same each time. Tamil Nadu GST registrations, the Rs 1 lakh intra-state e-way bill threshold and e-invoicing above Rs 5 crore are rebuilt in the new version and tested. Training and cutover briefings run in Tamil or English.

Data moves you can rerun and audit

Our specialists never migrate by hand. Each data load is a script in your repository, so it can be rerun after a fix, read by your auditor and reused when the next version arrives. Custom code is ported to current Odoo standards on the way through.

✓ Version moves up to Odoo 18 and 19

✓ Scripted imports kept in your repository

✓ Record counts and balances compared per run

✓ Custom modules ported to the current ORM

✓ Community to Enterprise moves handled

✓ Rollback steps written for cutover day

Frequently Asked Questions

We are on Odoo 12 in Chennai. Can we jump straight to Odoo 18?

Usually yes. Odoo's own upgrade service handles standard data, and we port custom modules and fix anything the upgrade leaves behind. We test the result on a copy, so you see Odoo 18 with your own records before deciding.

How do you make sure our balances match after migration?

Every load is followed by a comparison of trial balance, receivables, payables and stock value against the old system. Differences are explained in writing and fixed before the next rehearsal, and your finance head signs the final comparison.

Can we keep Tally running alongside Odoo for a while?

Yes, for a defined period. Some companies keep Tally for statutory books for a quarter while Odoo runs operations. We set an end date and a sync method so the two never drift apart unnoticed.

What happens to our custom modules during an upgrade?

We read each one and decide whether the new version already covers it. Modules still needed are rewritten for the new ORM and OWL front end, with tests, so they survive the next upgrade as well.

Will our Chennai auditor accept the migrated opening balances?

We prepare an audit pack with mapping sheets, opening balance reports and reconciliation notes. Auditors usually want to trace a sample of balances back to the source, and the pack is built so they can.

How much downtime should we expect on cutover?

Normally a weekend. Transactions stop on Friday evening, the final load and checks run over Saturday, and users start on Odoo on Monday. The rehearsals tell us the real timing well before the date.

Can our Ambattur and OMR offices go live on different dates?

Yes, if the data allows it. We can move one company or branch first and the next a few weeks later, though shared customers and stock between them often make a single cutover simpler.

Do you train staff in Tamil after the move?

Yes. Short role-wise sessions in Tamil or English cover what changed between the old system and the new one, so users learn the differences rather than the whole system again.
