After export site and imported in another scope workflow 2013 don't work and not associated with list
You should be aware of Exporting / Importing site does not preserve workflows, unfortunately, it's one of the disadvantages of the Exporting / Importing.
The alternatives workaround
- Use Backup-SPSite and Restore-SPSite for site collection instead of
Exportwhere this will ensure that everything is restored.
Or try to recreate the workflows manually by
- Opening the SharePoint designer in both source and destination site
- Create your list workflow, In source workflow
Select AllSteps and move it to the destination workflow.
- Or try to use 3rd party migration tool like sharegate, metalogix
- Or Use
Save Workflow as Templateas I mentioned at Backup & restore Designer workflow
