Out organization had a SharePoint 2010 site which was migrated to SharePoint 2013. All of its Nintex workflows were also been migrated few years back.
The workflows are running quite good. But any of the workflow is not visible in Workflow inventory. I have site collection admin access. I am able to view and edit new workflows but can see none of the migrated workflows. I can see all workflows and .xoml files associated to it using SharePoint designer. These workflows are located in NintexWorkflow folder.
I tried following things but that did not help:
1. Checked assiciated list id using SharePoint Designer, it is correct for all flows.
2. Tried opening the Nintex workflow, but it is not showing any of the existing workflows.
3. Tried opening AllItems.aspx for NintexWorkflows hidden document library, no luck. However this is opening in SharePoint Designer
I have tried opening inventory with Production as well as development license. Both the places behavior is same. Also tried with different browsers.
Please help on this.
