Business Central

From on-premises to Business Central online, without surprises

Your Business Central or NAV runs on your own servers. Updates get postponed, the server is due for replacement, and every upgrade is a project. You want to know whether the move to the cloud is possible, what it costs, and what can go wrong along the way.

The technical side of the move is well covered: Microsoft provides a cloud migration that copies data from your on-premises database to an online environment. It only brings across data from tables that also exist online. So customisation has to be available as an extension first, integrations have to move to OAuth, and reports and add-ons have to work online. That is where the real work is, and it starts with an honest scan.

When this fits

  • You run Business Central on-premises and the server or maintenance contract is coming to an end.
  • You are still on NAV or an old Business Central version with C/AL customisation.
  • Updates have been postponed for some time.
  • You have a migration proposal and want to know whether the scope is right.

What the engagement covers

  • Readiness scan: version, customisation, extensions, add-ons, integrations, reports and database size.
  • A decision per component: bring it across, replace it with standard functionality or an app, or drop it.
  • A migration path: straight through the cloud migration, or first upgrading and converting customisation to extensions.
  • Cleaning up data before the move, so you do not carry old ballast across.
  • A trial migration, and testing with your own scenarios.
  • A runbook for the cutover, including a fallback option.

What you get

First a well-founded decision, then a move that goes to plan.

  • A readiness report with findings, risks and an estimate of the effort.
  • A list of customisation and add-ons, with a decision on every line.
  • A migration plan with schedule and roles.
  • When carried out: a runbook, a test report and a handover.

What it is not

  • Not a reimplementation in disguise. If you want to redesign your processes, that is a separate decision.
  • Not hosting Business Central on-premises in a data centre of my own.
  • Not a promise that all customisation can come along. The scan shows what can and cannot.

Frequently asked questions

What does a readiness scan cost?

It is a defined engagement of a few days, depending on the amount of customisation and integrations. You get a fixed agreement on scope and price up front.

Can our old NAV version move straight to the cloud?

Not in one step. Older NAV versions first have to be upgraded to a version the cloud migration supports, and C/AL customisation has to be converted or replaced. The scan shows which path is shortest.

How long is the system unavailable?

The final synchronisation and checks usually happen over a weekend. A trial migration beforehand tells you how long that takes before it has to happen for real.

Is SaaS always cheaper?

Not always on the licence line, but usually overall: no servers of your own, no upgrade projects, and security and backups handled by Microsoft. The scan sets the costs of both situations side by side.
