A couple of days ago, Atlassian launched an app on the Marketplace called Cloud Migration Assistant for Confluence. It helps customers to move spaces between Server and Cloud in a seamless process (replacing need to manually export and import individual spaces).
This is a public beta, so it’s visible to customers. I wanted to share this with everyone because you may have customers that are trying it out, so best to be in the know. Please visit the app listing for more details about how this works, what it does, what it doesn’t do, etc.
I might also suggest giving it a whirl yourself, especially if you have a Confluence app in the Marketplace (either Server or Cloud), and sharing your experience/feedback as it pertains to your app.
