Issue
After migrating to a newer version of AEM, the error below is flooding the logs:

Environment
AEM 6.x
Cause
Workflow versions weren't migrated from the older AEM version so the workflow instances reference versions don't exist.
Resolution
- Go to the package manager (http://host:port/crx/packmgr/index.jsp).
- Create two separate backup packages, /etc/workflow/models (including the rep: policy node) and /etc/workflow/instances.
- Go to CRXDE (http://host:port/crx/de/index.jsp) and log in as admin.
- Browse /etc/workflow/models.
- Right click the /etc/workflow/models node and select Delete.
- Click Save All.
- Go to the package manager (http://host:port/crx/packmgr/index.jsp).
- Reinstall the package containing /etc/workflow/models.
- Install the attached package workflow-version-fix-tool-1.1.zip.
- Go to /apps/workflow-tools/workflowversionfix/run.html
- Run the script - this script resets all workflow instances to reference the newly reinstalled workflow model versions.
