I've got an old site running on Umbraco 8 with tons of content. I would like to create a new site most likely running on Umbraco 10. Upgrading seems close to impossible as there's a lot of stuff that isn't required. The problem I'm facing is how to: 1. Copy content from the old site to the new site? 2. Copy content from the old site to the new site but leave out some fields that are of no use. Do the document types and properties have to be exactly the same in Umbraco 10? Be great if someone could give some guidance?

I personally did the same, but I used Usync for it Export the Content on the old Site, Import it in the new site, delete the non-required properties

So if I have the doc types and properties already created in the new Umbraco 10 site, could I run Usync (free version) on the old site and then run the import on the new site?
