This How To article describes the steps needed to upgrade a Nintex for Office 365 approval workflow to Nintex Workflow Cloud and display the original list attachments within the task approval form. This scenario is one that the Nintex Upgrade Center team has encountered and Godwin Pamire, a technical specialist on the team, came up with this great solution.
You will see that some actions are unconfigured. Click the Workflow upgrade details link in the upper right corner of the screen. The Workflow upgrade details panel opens and displays the items requiring additional configuration prior to publishing.
The Assign a task action must be configured. Click the Design Form button to open the form designer. The form designer opens and displays the Forms upgrade details panel, displaying any items requiring additional configuration before the form is saved.
The form associated with the Assign a task action in NWC does not automatically display the related list item attachments.
Import the component workflow listed in the references below and then adjust your workflow to utilize the component workflow after upgrading:
Add and configure a Call a Workflow action
Adjust the Assign a Task Action to modify the task form to use the output variable from the Call a Workflow action
