Access to SQL Server or PostgreSQL
We rebuild relationships, indexes, and forms data into a cleaner structure, then test the new schema against your day-to-day reporting. No guessing. Just a safer path forward.
Data migration, ETL services, and legacy modernisation
Migrate Your Data Without Migraines
Still relying on Access or that one massive Excel file? It’s time for an upgrade that won’t break your business. We move critical records into modern SQL platforms with validation, transformation, and a calm rollout plan.
Common migration scenarios
We handle the trickiest migrations.
Access to SQL Server? Excel-based “databases” that need proper tables? Legacy ERP exports with odd delimiters? That’s the messy part we enjoy. Why let brittle files keep steering your reporting?
Spreadsheet to database
Those giant workbooks usually hold years of decisions. We normalise them into relational tables, remove duplicate entries, and keep the business rules intact. Who wants manual copy-paste forever?
Legacy ERP and CRM exports
Custom delimiters, half-broken date formats, missing IDs — all fixable. We map the source fields, validate them, and document every transformation so your team knows what changed.
Cloud-to-cloud sync and hybrid transfer
Need a safer bridge between systems? We build repeatable imports and exports that keep data moving without surprise overwrites. It’s steady, auditable work. Exactly what finance and operations need.
ETL workflow
Our ETL workflow: extract, transform, load.
The process stays transparent from first export to final sign-off. Want to know where a field changed, or why a row failed validation? You’ll have the answer ready.
Extract
We connect to legacy sources, flat files, APIs, and scheduled exports. Then we create a safe snapshot of the source data before anything moves.
Transform
Here’s where the cleanup happens. We de-duplicate, standardise, map to the new schema, and validate business rules without mangling the meaning.
Load
Bulk insert, incremental sync, and error logging are tuned to your platform. Need a dry run first? We do that too, because surprises are overrated.
Verify
Reconciliation reports confirm row counts, totals, and critical values. Your stakeholders sign off with confidence, not crossed fingers.
Tools and platforms
Tools we use for smooth transfers.
Some jobs need enterprise orchestration. Others need a lean DBeaver transfer, a Python script, and a clean rollback plan. Which tool fits best? We choose the one that keeps your data accurate and your budget sane.
SSIS and Azure Data Factory
Reliable for structured pipelines, scheduled loads, and repeatable enterprise flows.
Custom Python ETL
Perfect when the source data needs specialised logic, careful parsing, or practical automation.
DBeaver transfer features
Great for straightforward imports, exports, and database-to-database moves with minimal friction.
Pentaho and NiFi
Useful for budget-conscious projects that still need governance, monitoring, and repeatability.
Client story
We moved 15 years of data—without losing a single record.
Why did we choose Doug's SQL? Because they treated our old FoxPro system with care, rebuilt the structure cleanly, and kept our reports intact during the switch to SQL Server. The cutover was calm, the reconciliation was exact, and the documentation made training easy.
100% data integrity after migration. Five databases became one unified SQL Server instance.

Migration FAQs
Questions we hear all the time.
Messy data makes people nervous. Fair enough. Here’s how we reduce the risk and keep your team moving.
Will my existing reports still work?
Usually, yes. We map source fields carefully and test report dependencies before cutover so the business doesn’t lose access to familiar outputs.
How do you prevent data loss?
We use backups, validation checks, reconciliation reports, and staged migrations. Why gamble with the source of truth when we can verify it at each step?
Can you migrate while we’re still using the system?
Yes. For many clients, we plan a phased approach with incremental syncs so operations can continue until the final switch-over window.
What if my data is messy?
That’s normal. Duplicate records, missing values, and inconsistent dates are exactly the sort of issues ETL work is built to fix.
Do you provide training on the new system?
We do. Your team gets practical handover notes and clear documentation so they’re not stuck guessing after the migration is complete.
Ready to modernise?
Your data deserves a modern home.
