Ok I gave this a go on a test site with the uSync Migration - basically exporting in U7, then only copying the relevant document types, templates and Content over to U10 site, migrating and importing. It seemed to work to an extent. However it does not seem that you can map the content, for example if on v7 there is a News Article Style A, say, and on U10 there is News Article, Style B, you can't map from one to the other? You basically end up creating a News Article Style A on U10 and then populating that? So from what I can see I’d have to redo my news system Views/View Components etc once the news articles are all in. I don’t think this would be too onerous as the code is already there and it would just mean copying and pasting and creating new templates etc, hopefully
However just wondering if anyone knows would CMSImport be any easier for mapping content to existing document types - just want to be able to pass the word up the line. Thanks
