The new Atlassian App Migration Platform (currently under development) will enable all Atlassian Marketplace Partners apps to build automated migration paths for their apps.
When a customer migrates from Jira Server / Data Center, to Jira Cloud, using the Jira Cloud Migration Assistant, the app migration platform will programmatically migrate Zephyr Scale - Test Management for Jira and associated data from Server/DC to Cloud.
Please register here for the Zephyr Scale Migration EAP (early access program). http://go.atlassian.com/appmigrationseap
*As the customer EAP is Atlassian Supported and Solution Partner assisted, participation may not be guaranteed.
The SmartBear-Zephyr team is working toward v1.0 of the JCMA for Zephyr Scale.
If you are interested in beta-testing the JCMA prior to Atlassian's GA release then please contact Atlassian.
The SmartBear-Zephyr team is also collecting additional requirements from existing DC/Server customers for consideration in the JCMA.
Further information about migration support will be updated here in the near future.
