Specification

What data is migrated

Data	Note
WBS Code	Limitation On WBS Gantt-Chart for Jira server version WBS code of a issue can be set each WBS (Gantt WBS, Project WBS, Filter WBS). On the other hand, WBS code of a issue have to be unique on WBS Gantt-Chart for Jira cloud version. Therefore, If the same issue has WBS code on several WBS (e.g. Issue X’s WBS codes on Gantt A , on Gantt B and on Project C are different), used WBS Code is following priority. Newer Gantt > Older Gantt > Project > Newer Filter > Older Fileter
Template	Limitation Only fields of editable standard columns, successors and predecessors are migrated. Editable Standard Columns WBS code Name Assignee Units Priority Start Date Finish Date Manual Mode Due date Differences in specifications On WBS Gantt-Chart for Jira server version, templates are issues. On the other hand, on WBS Gantt-Chart for Jira cloud version, templates are app own data. Thus migrated issues for template are meaningless. So they are deleted automatically in migration process. And template issue type also.
