Workflow Scheme Migration
When the snapshot you are deploying includes:
changes in an active workflow scheme,
changes in a project(s) - workflow scheme association, or
changes in an active workflow,
an issue status migration might be required. The migration will ensure that the status of each issue in the affected projects is valid. Which statuses are valid for an issue is defined by its workflow. This means that when changing a workflow, you may need to tell Configuration Manager for Jira the status of specific issues after the change.
The screen for specifying the new status is the same as the native screen in Jira.
Duration of a workflow scheme migration
Workflow scheme migrations may slow down the deployment process significantly. The duration depends on the number of issues that are used by the changed workflow(s).
A rough guide: the migration of 200 000 issues takes about an hour.
