PandoratechOdoo migrations and upgrades without losing a single record
Move to a new Odoo installation or version with a documented data boundary, trial migration and reconciled opening position. We plan custom-module compatibility, attachments, cutover and post-launch checks around your operating needs.
Odoo migration moves agreed business data into a new installation or Odoo version while preserving the records needed to operate and report. Pandoratech scopes data extraction, mapping, trial imports, reconciliation and cutover. A database upgrade and a move from another accounting or ERP system need different technical and validation plans.

The challenge
Sound familiar?
Your accounting history is trapped in a legacy system
You’re several Odoo versions behind and support ended
A previous migration lost or corrupted data
Scope of the service
What's included
Platform migration
Chart of accounts, open balances, customers/suppliers, products, open orders, and document history where feasible — mapped, trial-migrated, and reconciled with your accountant before cutover.
Version and module review
Inventory custom code and dependencies, adapt them for the target version and rehearse the supported migration path.
Data validation
Compare control totals and representative documents, then document differences for finance and operations approval.
Attachments & documents
Files, PDFs, and message history migrated where the source allows.
Cutover and rollback planning
Agree the data freeze, final import, acceptance checks, decision owners and rollback route before production changes.
Post-launch checks
Review first transactions and integrations during the support period agreed for the migration project.

Choose the migration boundary deliberately
Not every old record needs to become a live transaction in the new ERP. Decide whether to migrate master data and opening balances, open sales and purchase documents, selected history or a complete compatible database. Historical attachments and audit access need a plan even when the old system remains read-only.
For a version upgrade, custom modules, integrations, report templates and third-party dependencies are inventoried first. For a move from another ERP, source exports and field definitions determine what can be mapped reliably. Missing data and inconsistent codes are documented as exceptions for the business to resolve.

Use trial runs and financial control totals
A trial migration lets finance compare receivables, payables, bank balances, tax balances and the trial balance before signing off. Warehouse teams compare quantities by location, units of measure and valuation. Totals are checked alongside representative documents because a correct overall balance can still hide an incorrectly mapped customer or product.
An illustrative mid-year cutover may carry open invoices with their outstanding amounts rather than recreate every settled transaction. The accountant approves the reporting implications, while users test how to receive payment, issue a credit note and retrieve supporting documents after migration. The agreed boundary is recorded in the handover.

Make cutover a controlled business event
The cutover plan names the final extraction time, the period when users stop entering transactions, the acceptance checks and the person authorised to proceed. It also states how to return to the previous system if critical checks fail. Downtime depends on database size, attachments, integrations and the chosen migration method.
After launch, check the first sales invoice, supplier payment, stock receipt and scheduled integration job. Keep the migration exception list and reconciliation report with the project records. Post-launch fixes should preserve the audit trail rather than silently change previously approved balances.

Frequently asked questions
Can we migrate without losing access to historical records?
Yes. The migration plan can include selected history, document attachments or a read-only archive of the previous system. These are different deliverables with different costs. Agree the retention period, access rights and report retrieval method with finance before deciding which history must be imported into Odoo.
How much downtime should we expect?
Most Odoo migrations are cut over across a single weekend, so invoicing resumes on the next business day. Downtime is estimated after a trial run using a representative dataset. The production window includes final extraction, import or upgrade, checks and a decision to proceed. A rehearsal gives a more reliable estimate than a general promise of zero downtime, particularly when large filestores or external systems are involved.
Will our custom modules work on the new version?
Not automatically. Custom modules need a compatibility review and may need changes before the migration. The inventory should include source code, licences, dependencies and the business tests for each extension. Migration approval should cover those workflows as well as the database opening successfully.
Can we move to Odoo during the financial year?
Yes. A mid-year migration is possible when finance approves the opening balances, tax reporting boundary and treatment of open documents. The team reconciles the source and target reports on the same cutover date. The appropriate approach depends on whether prior-period reporting will remain in the old system or move into Odoo.
Can we skip Odoo versions?
Yes. Pandoratech migrates across multiple Odoo versions in one planned hop — for example Odoo 14 directly to Odoo 19 — rather than upgrading one version at a time. We run Odoo 14 through 19 in production on our own infrastructure, so the version-specific breaking changes are known rather than discovered mid-project.
