Migrating Umbraco 8 to 9

So I just setup my shop in Umbraco 8 and noticed that Umbraco 9 is released… Soo, I’d like to upgrade my entire site.

I’m using Vendr shop and it’s compatible with Umbraco 9, luckily!

But my problem is - I have NO idéa how to move my content from Umbraco 8 to 9.

I know that I can’t upgrade from Umbraco 8 to 9, I need to create a new project and merge my content from the old database to the new one (installed with Umbraco 9). But how exactly do I do that?

Have any of you successfully moved data types, templates, pages etc. from Umbraco 8 to 9?

Also, when I run

dotnet add package Vendr

To install Vendr in Umbraco 9, the package area in the backend is empty.

Am I doing things completely wrong? I followed the installation guide from Installing Umbraco - Our Umbraco
