Earlier this year, Atlassian has announced the Server products would be sunset, with support for the affected products ending on February 2, 2024. You can learn more about this announcement on Atlassian's website.
The InVision apps for Jira and Confluence Cloud have the same features as the InVision apps for Server and Datacenter. After migrating to Atlassian Cloud, you will not find any differences when using the InVision app. All you'll have to do is to ensure you have the InVision app installed in your Cloud instance.
Migration path for the InVision app for Jira
The migration of the InVision App for Jira Server and Datacenter is not automated yet. Here's the roadmap for the automation:
Automatic migration of attached InVision prototypes
Automatic migration of App project configuration
