I have a multisite setup with a pages section. In the future we want to add additional sites but there seem to be some caveats. When we first setup pages we set the section propagation to 'all other sites in this group'. This creates the pages we want in another site without having to recreate the content. Great :)
Once this has been done, I then change the section settings to 'only save sites they were created in'. Otherwise the content edited overwrites each site page. However, I am trying to achieve a cookie cutter approach going forward that lets us set up a new site and then allows us to copy initial pages in the section rather than recreate the existing pages for the new site.
However there is an inherent danger in swapping propagation methods as this seems to sometimes remove content and or create failed tasks where I can't tell what craft is trying to do (maybe a bug - I'll check github later)
Is there a better way of achieving this process over time when adding sites or is best to just complete initial setup then leave and add new site and content from scratch?
