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.

FAQ
Can you migrate DBF / Clipper files?
Yes. I wrote business software in Clipper for 15 years, so old DBF data and its quirks are familiar to me.
What if the data has errors?
Errors are reported in a separate list for you to decide, never dropped silently.
Is my data safe?
I work on a copy, sign an NDA if needed and delete your data after delivery.
