SQL Server upgrades
In-place or side-by-side upgrades from SQL Server 2016 and older to SQL Server 2025, with compatibility testing and a rollback plan.
Data platform modernisation & migration
Out of support?
Move without the drama.
SQL Server 2016 left extended support in July 2026. We upgrade and migrate your databases, ETL and reports to supported, modern platforms — on-premises, on Azure or AWS, or in Microsoft Fabric — with every step rehearsed and reconciled.

Legacy platforms
get riskier every month.
No more security patches
SQL Server 2016 and older versions no longer get security updates — a growing audit and security risk.
Rising licence and hardware costs
Ageing servers and over-provisioned licences cost more every year than the platform is worth.
Shrinking know-how
Fewer people understand the old ETL and reporting stack, and the ones who do are stretched thin.
Fear of downtime
Migrations keep getting postponed because nobody can guarantee the business keeps running during the move.
Every migration path.
From database to dashboard.
02
Cloud migration
Databases moved to Azure SQL, Azure SQL Managed Instance, Amazon RDS or cloud VMs — sized from real workload data, not guesswork.
03
Oracle to PostgreSQL
Schema and code conversion, data migration and performance tuning, so you can leave expensive licences behind without losing functionality.
04
ETL modernisation
SSIS and legacy ETL inventoried, rationalised and moved to Microsoft Fabric pipelines in priority order, with outputs reconciled.
05
Warehouse to Fabric
Synapse and on-premises warehouses moved to a Fabric lakehouse or warehouse, keeping reports working throughout the move.
06
Reporting modernisation
SSRS and Power BI Premium content moved to Power BI and Fabric capacity, keeping paginated reports where they still make sense.
We know both sides of the move
We know the platforms you're leaving as well as the ones you're moving to. Years of running SQL Server, Oracle and PostgreSQL in production are what make our migrations predictable.
Start small.
Scale with confidence.
01 · Assess2–4 weeks
Migration assessment
Inventory, dependency mapping and compatibility checks, ending in a target design, a cost comparison and a cut-over plan you can take to the board.
What you get
- Inventory of databases, ETL and reports, with dependencies
- Target platform design and cost comparison
- Phased plan with risks and rollback points
02 · BuildPer wave
Migration in waves
We migrate in small, reversible waves — rehearsed in test, reconciled after every move and cut over in agreed maintenance windows.
What you get
- Migrated and tested databases, pipelines and reports
- Data reconciliation report for every wave
- Cut-over runbooks and rollback plans
03 · RunMonthly
Post-migration care
After go-live, our 24/7 DBA team monitors performance, tunes the new platform and keeps costs in check.
What you get
- 24/7 monitoring with Avesys
- Performance tuning on the new platform
- Monthly cost and capacity review
Migrations run by people who run databases
Since 2019 our DBAs have kept enterprise databases running around the clock. We bring that operational discipline — rehearsals, runbooks, rollback plans — to every migration.

Frequently asked questions
Our SQL Server 2016 is out of support. What are our options?
Upgrade to SQL Server 2025 on your own infrastructure, move to Azure SQL Managed Instance or a cloud VM, or buy Extended Security Updates as a bridge while you plan. We compare cost and risk for each option before you decide.
How much downtime should we expect?
Usually minutes, scheduled in a maintenance window. We keep the new platform in sync with replication or log shipping and switch over only after the reconciliation checks pass.
Is moving from Oracle to PostgreSQL realistic for us?
For many workloads, yes. The assessment flags features without a direct PostgreSQL equivalent and estimates the conversion effort, so you know the true cost before committing.
Do we have to move to the cloud?
No. Modernisation can mean a supported on-premises version, the cloud or a mix of both. We recommend what fits your regulations, data residency needs and budget — including in-country hosting where BDDK (Turkey's banking regulator) or sector rules require it.
Will our applications and reports keep working?
That is what reconciliation is for. In every wave we test applications and reports against the new platform, compare the results with the old one and cut over only when they match.
