Running Newers Database Versions on an older Exadata CRS

User_0Y97W

We currently have several Oracle Exadata servers running CRS/GI 12.2.0.1 with October Patchset.

We are planning to start using from 12.2.0.3 19c databases but without upgrading the grid infrastructure.

We wondered if this is:

• possible
• supported/certified
• 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.

Hi,

always the highest Version on a Grid / RDBMS Environment is on the Grid Software.

So can't upgrade or use higher Version for RDBMS when the GRID is a lower Version. unpossible!

You need first to upgrade the GI Software

All is written in 888828.1 Doc-ID the Bible :-)

Check before Upgrade "Patches to apply before doing upgrades" 253975.1 very important
