About this Gig

Moving from an old system to a new one? The hard part is not copying tables. It is making sure customer balances, stock and accounts are exactly the same on the other side.


I have migrated many companies from other vendors' systems into the ERPs I develop: customers, suppliers, items, prices, stock, open invoices and payments, with reconciliation reports so nothing is lost.


Sources: Firebird/InterBase, SQL Server, MySQL, PostgreSQL, Access, DBF/Clipper/FoxPro files, Excel and CSV.

Targets: Firebird, PostgreSQL, SQL Server, MySQL, or the import format of your new system.


What you get:

  • Mapping document: old field to new field, with the rules applied
  • Repeatable migration scripts, so the final cut-over is quick
  • Reconciliation report: totals and balances, old against new
  • List of rejected or suspicious records to review


Please message me with the source and target systems before ordering.
