Running Newers Database Versions on an older Exadata CRS
We currently have several Oracle Exadata servers running CRS/GI 126.96.36.199 with October Patchset.
We are planning to start using from 188.8.131.52 19c databases but without upgrading the grid infrastructure.
We wondered if this is:
- good idea
Or if we should just upgrade the infrastructure to 19c and be done with it.
The reason for the above is the effort to get the grid infrastructure upgraded i.e. change control, getting budget to do it and scheduling supplier resources is painful and I'd rather do this at a later date.
Any advice/experience of this appreciated.
