Exadata with different GI and RDBMS versions - supported?
We are planning an Upgrade of two 1/8 Exadata racks, which are currently running 11R2 Databases.

After this, GI and installed RDBMS will run databases in the same Version 11.2.0.3 for a while, until the DB Team takes over and continue the upgrade in the DB field. There is no way to avoid this two-step
