I noticed on this issue from last year where Laurent Nicolas commented: "This is an ONTAP limitation. The REST APIs only manages data vservers and hide system resources. Root aggregates are also hidden. This is an effort to simplify and hide some of the ONTAP complexity."
https://github.com/ansible-collections/netapp.ontap/issues/120
If REST hides the "ONTAP complexity" then how can we do complex things? Right now I have Day 0 playbooks that do complex things such as renaming root aggregates. If this wont be viable in the future then what is the path forward?
