Upgrade questions
How long does an upgrade take?
Typically about three weeks from start to go-live. Sites with a lot of custom code, integrations or packages that need replacing take longer, and your free upgrade check gives you a clear estimate before you commit.
Will our editors need retraining?
As little as possible. Your content and the way it's organised stay the same, so editors find everything where they left it, in a backoffice Umbraco has made cleaner and quicker to use.
Can you upgrade a site another agency built?
Yes. The free upgrade check tells us everything we need to know before we quote.
