How to duplicate EazyBi instance to UAT/Staging instance (migration procedure)

I need to refresh staging jira + addons (eazybi etc) with the production.
I checked the migration procedure here and wanted to be sure :

  • Staging/UAT addon will only duplicate production data to its own staging db ? It will not remain / stay connected to Prod instance ?
  • No data will be deleted from Prod ?

Thank you.
