The 1st SNAPSHOT for Minyaa Workflows is available.
It is not yet a Beta version, since Minyaa Time migration is causing always some refactorisation.

If you want test it without Minyaa data on a fresh JIRA Instance, you can use directly the 7000.1.0-SNAPSHOT on JIRA 7.0.0 to 7.0.5 (Not yet tested on higher versions).
If you want test it with Minyaa Workflows data, you have to process as follow :

• Upgrade your JIRA to JIRA 6.4.x, at least 6.4.6 or over (6.4.12) with Minyaa 3.5.2
• Deploy jira-plugin-minyaa-workflows in 6400.1.0-SNAPSHOT (Workflows will be converted by internal Upgrade Tasks)
• Apply the Temporary License key file
• Uninstall Minyaa 3.5.2
• Stop JIRA and remove all traces of Minyaa 3.5.2
  • JAR Files,
  • Altered jsp files *.jsp.myaa should have been restored into *.jsp

    <JIRA_INSTALL>/atlassian-jira/secure/createissue-details.jsp.myaa 
    <JIRA_INSTALL>/atlassian-jira/includes/objectconfiguration_form.jsp.myaa 
    <JIRA_INSTALL>/atlassian-jira/secure/admin/views/viewworkflowsteps.jsp.myaa
    <JIRA_INSTALL>/atlassian-jira/secure/admin/views/viewworkflowtransition.jsp.myaa
    

• Restart JIRA

Then, you can migrate to JIRA 7.0.x following one of below method :

• Using the a XML Backup (done after above operation). It should not contains traces of added Minyaa entities : WorklogType, WorklogExt, TimesheetScheme, TimesheetScheme, LinkScheme, LinkEntity, ReportScheme, ReportEntity, MyaaConstantMapping
• Or using a direct Database migration by switching to the 6.4.x database your new JIRA 7.0.x instance.

Note that it is always a SNAPSHOT release and have to be tested only in Test environment.
