Map Nintex workflow actions
Actions from on-prem that are not supported by Office 365 are replaced by placeholders because we can't be certain the the logic will work. We could offer some sort of action mappings to help some clients fix the issue during the migration when there's many workflows involved.
Victor shared this idea
We are just releasing now the possibility to convert Action Set (on-premises) to Run If (O365). Since the Action Set workflow activity does not exist in the O365 version of Nintex Workflow, this is the closest / best we could do to preserve the encapsulated inner actions.
