Migration 6: Why Legacy Database Projects Take Longer Than You’d Expect — And Why That Works in Your Favour
A Question We Get Asked a Lot
How long will this take?
The honest answer is: longer than you might expect. A straightforward migration from a legacy system to a modern cloud-hosted application will usually take several months, from the first conversation to go-live. A larger or more complex project may take longer.
Before that puts you off, it is worth explaining what that time actually involves – and why the timeline often works in your favour.
The Complexity Is on Our Side, Not Yours
The first thing to understand is that most of the complexity sits with us, not with you. Your job is to tell us how your organisation works. Our job is to understand it, build the new system, and make sure it is right before you switch over.
We have done this before. We know what to look for, what questions to ask, and where problems usually hide in an old Access or FoxPro database. We do not need you to understand databases. We need you to understand your own organisation – and you already do.
Why the Timeline Is Longer Than You’d Expect
Not all of the time is spent building. Much of it is in understanding, checking, and making sure the system works properly for the people who rely on it.
Understanding the System
The people who know the old system best – which reports matter, which records are critical, and which workflows have quirks – are often busy people. They already have a job to do, and a migration adds another demand on top of it.
We work around that. We ask questions in small batches, document what we learn, and come back to verify details as the project develops. Done properly, that takes time.
Getting Information Out of the Old System
Legacy databases do not always cooperate. Data may be stored in awkward formats.
Relationships between records may need to be rebuilt. Some information may need to be cleaned up or restructured before it can be moved.
We handle all of that, but it is not a one-afternoon job.
Building and Testing
We build the new system in stages and test it as we go. We share progress with you regularly so you can see how it is developing and flag anything that does not match how your organisation actually works.
That approach takes more time than disappearing for a few months and returning with a finished product, but it almost always leads to a better result.
Parallel Running
For larger projects, we often run both systems side by side for a period, typically in the final months before go live. This lets us check that the new system matches the old one record by record and gives your organisation confidence that nothing has been lost in the move.
What the Process Looks Like
Here is a typical project flow:
- Initial conversation: we talk through your current system, understand the basics, and give you an honest first view. There is no charge for this.
- Review and quote: We assess the system properly and provide a written quote with a timeline. There is no obligation to proceed.
- Agreement and start: if you decide to go ahead, we agree on the timeline and begin.
- Regular check-ins: usually every couple of weeks, with a standing slot such as a Friday morning to answer questions and review progress. Questions can be emailed in advance so we can come prepared.
- Incremental build: you see the system taking shape as it develops. Nothing is hidden until the end.
- Parallel running: both systems run together while the new one is checked against the old.
- Go live: you switch to the new system. The old one remains accessible for a period as a safety net.
- Ongoing support: we do not disappear after launch. We are available for updates, changes, and anything else that needs attention.
What Your Staff Will Experience
Very little, and that is intentional. We work with the people who know the system, but we structure the project to minimise disruption for everyone else.
Staff who use the system day to day will be involved in testing before go live, but they will not be expected to sit through long meetings or understand technical details. Their job is simply to tell us if something does not work the way they expect.
When they switch to the new system, it should feel familiar. We build modern systems that mirror the workflow of the old one, so the learning curve is kept as shallow as possible.
This Is Not a Complicated Process for You
We want to be clear about this. Yes, migrating a legacy database is a technical undertaking. But it does not need to feel complicated from your side.
You are not expected to understand the technology. You are not expected to project manage a development team. You are expected to answer some questions about how your organisation works, review what we build, and tell us whether it is right.
The rest is our job, and we are good at it.
