Legacy Migration — QuickBooks · Sage · Dynamics 365

Done with your old system? Move cleanly.

Most businesses stay on software they have outgrown because moving feels riskier than staying. It does not have to. We audit your data before anything moves, run a test migration you validate yourself, keep your old system running in parallel until cutover, and go live on a date you control. Nothing disappears. Nothing breaks without warning.

The real reason businesses wait

It is not logic that keeps you
on old software. It is fear.

Every objection we hear has a direct answer. Here is what we say — and why it is true.

"We have been on QuickBooks for 10 years. What if something goes wrong?"

A test migration you approve before a single thing changes in production. You see exactly what transfers, what it looks like in Odoo, and what stays in an archive. Nothing moves until you say so.

"We can't afford the disruption. Our team is already stretched."

A parallel-run migration means your team stays on the current system through testing and training. They switch on a date they are ready for. The cutover window is typically a weekend, not a shutdown.

"What about all our historical data?"

Most businesses do not need 10 years of transaction history in their active ERP. Open balances and recent history cover nearly every day-to-day lookup. We help you decide what migrates and what is better archived.

"We tried this once before and it was a disaster."

Most ERP migration failures share the same cause: data moved without an audit, the test migration was skipped to save time, or go-live happened before the team was trained. We do not skip those steps.

Systems we migrate from

The accounting software Canadian
businesses actually run on.

We migrate from the platforms Canadian SMBs are most likely to outgrow. If yours is not listed, get in touch — the methodology applies broadly.

QuickBooks Desktop & Online

Chart of accounts, customer and vendor master, open invoices, AR/AP balances, bank accounts. Historical transactions available where needed.

Sage 50 / Sage 300

Full account structure, AR/AP aging, inventory records, customer and vendor master, historical transactions, payroll history where applicable.

Dynamics 365 Business Central

Financial entities, open sales and purchase orders, customer and item master, account balances, multi-entity structures where present.

Spreadsheets & manual systems

Customer lists, product catalogues, pricing matrices, inventory snapshots — structured and cleaned into Odoo master data in a format that lasts.

Migration process

Six steps from your old system
to a live Odoo environment.

Every step has a visible output you approve before we move forward. Nothing proceeds on trust alone. Read our full methodology.

01
Data audit
Before anything moves, we export and review your existing data — customers, vendors, chart of accounts, open transactions, balances. We document what is clean, what needs remediation, and what is safe to leave behind. You approve the migration scope in writing before work begins.
02
Chart of accounts mapping
Your existing account structure gets mapped to Odoo. We flag mismatches, recommend where a cleaner structure makes sense, and document every decision. The chart of accounts is the foundation everything else sits on — getting it right here prevents problems that are very expensive to fix later.
03
Odoo configuration
We configure Odoo around how your business actually operates: your tax setup (GST, HST, PST), payment terms, fiscal year, currency, and the specific workflows your team depends on. Migration and implementation run in parallel — you are not waiting for one to finish before the other begins.
04
Test migration & validation
We migrate your data into a test environment and run the numbers. Trial balance, open receivables, open payables, inventory on hand. You review and approve the test migration before anything goes near production. If the numbers do not reconcile, we do not proceed.
05
Training on real data
Your team learns Odoo on the test environment using your actual migrated records. Training on real data — your customers, your products, your invoices — sticks in a way that a demo environment never does. Your SPoC trains the rest of the team in their own processes.
06
Cutover & go live
We do a final data sync close to your cutover date, flip the switch on the agreed date, and stay hands-on through the first weeks live. Your old system remains accessible in read-only mode until you are confident you do not need it. We do not push go-live back chasing perfection — a live system that improves beats a delayed one every time.
What to expect

Honest things nobody tells you
about ERP migrations.

Things we tell every client upfront — because finding out mid-migration is worse than knowing before you start.

Your data is messier than you think.

Duplicate customers, account codes from 2014, years of workarounds normalized into the system. Every data audit finds this. A migration is your best chance to clean it up rather than importing the mess into a new system.

A mid-year cutover is almost always fine.

Businesses delay waiting for a year-end that never feels right. Most mid-year cutovers work well with careful balance mapping and a committed cutover date. What matters is reconciled numbers — not the calendar.

You probably do not need 10 years of history in Odoo.

Open balances and 12–24 months of transactions cover nearly every practical lookup. Historical data is better in a read-only export of the old system — accessible when needed, out of the way when not.

Parallel running has a cost.

Running both systems during testing means double-entry for a period. We keep that window short and structure training to minimize it. The safest migration goes live at a clean moment — not dragged out because cutover feels scary.
