Redirects work similarly to as you would handle them in a regular project. However, for the enterprise group, child redirects will be omitted and the enterprise group will be taking into consideration.
If you have child redirects configured for your enterprise project, move your redirects to the enterprise dashboard and be sure to include the child project subdomain in the redirect
For example, in a single project it is sufficient to write:
/docs/this -> /docs/that
but in the Enterprise Parent Group you must include the child project subdomain:
/projectname/docs/this -> /projectname/docs/that
