This information correct as of October 2021
The JSU team is pleased to announce that JSU will be compatible with Atlassian’s public beta for App-migrations using the Jira Cloud Migration Assistant (JCMA). This means that for the first time ever, you’ll be able to automatically migrate most of your JSU workflow automations from your Server instance to your Cloud instance.
Please note, app-compatibility with JCMA is still in it’s early stages. JSU is taking part in Atlassian’s public beta to offer customers early-access to the functionality and so that we may get feedback on the migration experience by participating customers. This means that while we strive for functionality that works 100% as intended, there may be undiscovered issues as we test and improve the compatibility. Additionally, due to some feature differences between JSU Server and JSU Cloud, not all features can be migrated at this time.
