If you'd like to migrate old (prior 2.3.9) gadgets to to new, it's possible to do it manually.

Analyze DB, find 'portletconfiguration' and 'gadgetuserpreference' tables.

In old Jira portletconfiguration.GADGET_XML you should see values:

- rest/gadgets/1.0/g/jira-timesheet-plugin:timesheet-gadget/gadget.xml (old)
- rest/gadgets/1.0/g/jira-timesheet-plugin:group-timesheet-gadget/group-timesheet-gadget.xml (group)

In new Jira portletconfiguration.GADGET_XML you should see value:

- rest/gadgets/1.0/g/jira-timesheet-plugin:timesheet-gadget/timesheet-gadget.xml (new)

In gadgetuserpreference DB table see USERPREFKEY values for the particular gadgets:

- num_weeks
- reporting_day
- user
- group
- isConfigured
- projectOrFilter

You can perform these steps for migration:

1. Rename portletconfiguration.GADGET_XML to rest/gadgets/1.0/g/jira-timesheet-plugin:timesheet-gadget/timesheet-gadget.xml for old and group gadgets
2. In gadgetuserpreference DB table:
3. For old gadget:
   • leave 'reporting_day' field as it is
   • leave 'num_weeks' field as it is
   • leave 'user' field as it is
   • create sumSubTasks field with value: 'false'
   • create isConfigured field with value: 'true'
   • create projectOrFilter field with value: ''
   • create showIssues field with value: 'true'
   • create 'group' field with value: ''
   • create 'projectRole' with value: '<some ID from projectrole DB table>'
4. For group gadget:
   • leave 'reporting_day' field as it is
   • leave 'num_weeks' field as it is
   • leave 'group' field as it is
   • leave 'isConfigured ' field as it is
   • leave 'projectOrFilter ' field as it is
   • create sumSubTasks field with value: 'false'
   • create showIssues field with value: 'true'
   • create 'user' field with value: ''
   • create 'projectRole' with value: '<some ID from projectrole DB table>'

Note, there is no need to create missing preferences, gadgets should work out defaults, end user later may adjust missing settings.
