I followed the procedure, deactivated the feature in each site, deactive the solutions and loaded the new wsp. I cleaned the sharepoint designer cache and updated it.
The new workflows work. But previously created workflows (2.8version) do not work. The error is “The associated workflow has been deprecated”. And in “sharepoin designer” it shows the following error “Failed to load this workflow To correct this problem, restart Sharepoint Designer”.
Can you help me with this case?
