Legacy migrations are where most modernization programmes get stuck — too risky to attack head-on, too painful to leave alone. We do them in stages, with the legacy stack running until the new one is provably better.
The old platform still runs the business — that's exactly the problem. Every new project pays a toll in workarounds, every integration takes months, and the people who understood the system are leaving faster than it's being replaced.
A head-on rewrite is a bet nobody wants to sign. Leaving it alone costs more every year.
We migrate in stages, with the legacy stack running until the new platform is provably better — reconciliation on every load, and an exit test the business signs off at each stage.
Warehouse to lakehouse, on-prem to cloud, unmaintainable app to supported stack — the pattern is the same: no big-bang weekend, no leap of faith.
Removes a maintenance tax that grows every year. Unblocks the next platform investment. Gets the team out of firefighting and back to building.
Mid maturity. The right moment is when the legacy stack is blocking the next initiative — ML, real-time, group reporting — rather than as a standalone modernisation.
Where this lands in practice. Each row opens with the detail — and what it buys you.
Phased migration with the legacy DWH running until the lakehouse parity is proven. Reconciliation on every load.
The payoff. A migration nobody downstream notices — until the reports get faster.
The SQL Server-era stack — integration packages, analysis models, paginated reports — moved onto the modern platform: dbt / Fabric / Databricks underneath, Power BI on top. The dimensional model and report logic carry over intact, not rebuilt from memory.
The payoff. Twenty years of BI logic preserved; the platform behind it renewed.
Lift the estate to the cloud in stages — landing zone first, workloads second, optimisation third. The business keeps running through every stage.
The payoff. The datacentre empties without a single big-bang weekend.
Excel / Access / file-share reports rebuilt against the governed semantic layer with no loss of the existing logic.
The payoff. The report that ran on one person's laptop now runs the business.
The business app everyone depends on and no one dares touch — frameworks out of support, the last person who understood it long gone. We modernise it in slices: stabilise, cover with tests, then move piece by piece to a supported, maintainable stack.
The payoff. The app nobody dared touch becomes just another system.
Nightly file drops, point-to-point links, logic living in the integration itself. We replace the spaghetti with a clean API and event layer — so systems can finally be swapped without six months of side effects.
The payoff. The next migration costs a fraction of this one.
Through the Moberg Delivery Framework — the same five stages, governance and engineering standards we run on every engagement, from business case to long-term run. This is exactly the work Microsoft has independently validated us for — but the real assurance is old and new running side by side until the numbers match.
