When attempting to copy an item, Sharegate displays one of the following errors:
The content type is generated by Nintex on Office 365 and cannot be migrated.
The column is generated by Nintex on Office 365 and cannot be migrated.
Nintex generated some content types and columns for specific workflows. This error occurs when trying to migrate an item that uses one of those content types or columns. This usually happens in the case of a list that uses Nintex Task Outcomes.
The specified content types and columns cannot be migrated, and if they are needed at the destination, they should be generated by activating the required Nintex features.
