Up-gradation of grid infrastructure on Exadata X7-2 from 18c to 19c.

Current config is as fol:-
Machine: Exadata X7-2
Grid infrastructure - 18c
Database - 11.2.0.4

I need to upgrade the database on 19c.

First question: Can 19C be configured on grid 18c?
Second question: How to upgrade grid infrastructure 18c to 19c on Exadata X7-2
Third question: Is it possible that i can run database 11.2.0.4 and 19c (both at the same time)under grid infrastructure 18c and 19c.

Thanks & Regards
