uSync Migrations not converting all properties

I’m trying to upgrade my Umbraco website from Umbraco 10 to Umbraco 13. To use the new BlockGrids and BlockLists I want to make use of uSync.Migrations because a colleague used it in a previous upgrade and had very few issues. Because the colleague proposed it, I wanted to use it in my project as well for a quick deployment. I fixed it on my local development, but when I’m trying to deploy the content to my test environment I see a lot of content failing. I’m now trying to migrate the prod content on my local machine and import it on the next environment, but also a lot of bugs here.
Points where I hit a wall:

  • Imported content with the new properties but not seeing the content in V13
  • Properties like HeadingLevel (dropdown) had value of e.g. 2, but they need to have “Heading 2”
  • Adjusted content on my local machine but not seeing it update when I click Report

What I would like to see is if people encountered the same issues or have a nice step by step walkthrough of what they did in their migration.
If another take on the Umbraco migration from 10 → 13 can help me forward, I would like to here it as well.

Thanks in advance.
