Minimun certified exadata stack version for GRID INFRA version 19.7.0.0.200414

Hi.

We have two environments with characteristics:

1) EXADATA STACK version: Image version: 19.3.7.0.0.200428

   GRID/CRS/BBDD version: 19.7.0.0.200414 (30869156):

We need have same version of GRID INFRA in other environment with those characteristics:

2) Version STACK EXADATA: Image version: 19.1.2.0.0.190111

  GRID/CRS/BBDD  Version: 12.2.0.1.200114 (JAN 2020)

Question is:

If we upgrade GRID to 19.7.0.0.200414 version, exadata stack 19.1.2.0.0.190111 is compatible and certified for this new GRID version or is necessary upgrade exadata stack too?

Thx

Regards
