We have an engagement that we have tracked via our Jira, but the client is now considering subscribing directly to Atlassian. They have asked to know the size of the existing Jira Project and Confluence Space, as they would potentially like to migrate it to their account.
Is there a way to tell them the approximate size of the Project and Space? Additionally, the ability to export a single project does not seem to exist, so I assume the best course of action would be to mass export all issues and import them via csv?
