I am currently exploring options for upgrading an Umbraco site with version 8.18.11 to version 13. The site doesn’t have any packages, is available in 3 languages, has multiple (20+) forms, thousands of media files and numerous pages.

From what I’ve read there doesn’t seem to be a clear direct upgrade path however I don’t really know where to start. I have a feeling the pain points will come from the .NET Framework to .NET Core update.
