We are fully committed to enable every Scroll Versions user to migrate to Confluence Cloud and Scroll Documents. We are currently working to improve feature parity between the two apps and to provide an automated migration path.
A later migration will give you a more complete feature set to start with and an easier migration path. For this reason we'd like to ask you to delay the migration.
However, some of our users have performed a manual migration from Scroll Versions and Confluence Server to Scroll Documents and Confluence Cloud with help of our product support. So if you're forced to migrate right now, please reach out to us under firstname.lastname@example.org.
