Grote Migratie

Still working with an older version of Umbraco? Then you know: the end of support is drawing nearer. Versions 7 and 8 are already out of development, and version 10 has just retired. It's high time to take action.

Yet, we often hear that organisations dread such a transition. Because it seems complicated. Or because they think they have to choose between rebuilding everything or replicating everything exactly. That is simply not true.

At Webwonders, we rebuild your website from a clean slate. At the same time, we migrate all your old content – automated, smart, and future-proof. No manual work, no technical hassle, no decision stress.

Why switching seems daunting (but isn’t)

Many agencies stick to one of two approaches: either they rebuild everything from scratch and leave your archive behind, or they copy everything one-to-one and bring along the old clutter.

We do it differently. We combine both. We build a new foundation and we bring along everything valuable – but in a form that is ready for the future.

You don't have to choose. You get a new site AND all your content – in one logical, workable environment.

Our approach in 6 steps

No jargon, no detours. Simply explained clearly.

  1. We rebuild your website from a clean basis
    No upgrade over old clutter, but a fresh installation of the latest Umbraco version. Clean, fast, and ready for the future.

  2. We redesign everything
    We create a smart and logical content model, tailored to what you need now. Not a copy of your old site, but an improved version.

  3. We automatically migrate your content to the new model
    Do you have a large news archive or many pages? We ensure everything is transferred automatically. Not one by one, but in one smart move.

  4. We translate outdated elements to modern standards
    We replace old custom fields or self-built solutions with stable, standard components. This makes your website faster and easier to manage.

  5. We combine old and new in one clear structure
    Your entire archive gets a place in the new design. Everything looks like a cohesive whole. Meanwhile, new articles benefit from modern features, such as tags, filters, or links.

  6. We go live without stress
    Once everything is tested and works, we switch the site over. Your editors can get back to work immediately. No double work. No data loss. No downtime.

The result: a hybrid solution that works

  • Your entire archive remains intact

  • Old articles are automatically displayed in the new design

  • New articles have additional features and smart functions

  • Everything feels like a cohesive whole to your visitors

  • Your editors work faster and easier

  • Your site is technically ready for what lies ahead

A practical example

A large national industry organisation wanted to switch to a modern Umbraco version. They had a significant amount of content built in an old system with custom fields.

We rebuilt everything from scratch. At the same time, we automatically transferred their entire archive. The result? One cohesive website. Old news and new articles in the same style. The editorial team works faster, visitors notice no difference, and the technology can last for years to come.

Ready to upgrade without worries?

Moving away from old systems doesn’t mean starting over with empty hands.

At Webwonders, we ensure that your old content is carried over, but in a new form. So you can move forward without hassle.
