I am trying to replace our out-dated SharePoint Designer worfklow (SharePoint 2010 approval workflow) with Nintex solution. However, I was unable to find the option to create the workflow template and re-use it across all sub-site Document Library.
We have the approval workflow on top site collection level, any Document Library in sub-sites under that site collection can use the workflow. When I need to make any change, I only needs to open SP Designer and change the workflow template at top level.
Is that a feature that Nintex support? I am using trial version and I cannot find it.
Unfortunately not. There is no such thing. The only option I see is to use Nintex O365 REST API and "Import into a new workflow" method (https://help.nintex.com/en-US/sdks/sdko365/#Reference/REST/NWO_REF_REST_ImportWorkflowPost.htm%3FToc...).
This way you can have a definition of your workflow on a top site collection level and propagate it using a script to libraries in subsites. However be aware, that this method does not change the workflow's name, so it will create a new workflow in the destination library with the same name as the source one. And you can't use it for more than one library in the same subsite
