Since many workflows are started by, or perform changes in SharePoint® content – perhaps a new list item fires a workflow process, or a process modifies a library – upgrading to SharePoint 2013 can break your workflow processes.
The introduction of Microsoft’s new Workflow Manager, and the separation of the workflow engine from SharePoint 2013, have downstream impacts on users of business process management software (BPMS), like Nintex Workflow and K2 blackpearl®.
For users of SharePoint 2010 looking to upgrade their Nintex Workflow solutions to use the new platform and its features, staying current with SharePoint can mean refactoring workflow processes or even shifting Nintex solutions altogether. Although it is possible for SharePoint 2010-based Nintex solutions to run “as-is” in SharePoint 2013, this capability may not extend beyond the 2013 edition.
Nintex customers will have more decisions to make.
Since rebuilding 2010-based workflows is effectively a given (it’s just a question of when), perhaps building them in a mature BPMS independent of SharePoint, and its new and presently incomplete workflow engine, is worthy of consideration.
