We recently were demerging with another company and as such had to split our JIRA cloud site. We started a brand new one and started using it, not realising the ideal way to separate the site is to migrate what we need from the existing site first. So at the time we got to migrating the projects over we already had an existing JIRA Software site with projects and issues and Confluence site with pages. Is there any way to merge the 2 sites? In the end we had to start a whole new instance as we couldn't migrate projects from the existing instance in to the new one.
These are the methods we tried (we want to retain activity, comments and attachments so export/import via csv is not an option)

And as in this article, I don't believe to date there is a straight forward way to do

Wondering if anyone has answers to this?
