When trying to copy a Nintex workflow, Sharegate displays the following warning:
A Nintex user defined action could not be created at "Farm" level. It was created at the "Site collection" level instead.
|Any error code ending with: -177|
This error occurs when copying a Nintex workflow containing a user-defined action. The error means that Sharegate was unable to create the user-defined action in the same scope as it was at the source (either at the Site Collection or Farm level), so it was instead created in a lower scope (either Site or Site Collection).
Make sure you have sufficient permissions at the destination to promote a user-defined action to the Site Collection or Farm level. Once you have the permissions, you can either manually promote the user-defined action at the destination to send it to the right scope, or retry the migration.
