I have Grid Infrastructure version 220.127.116.11 with ASM running on linux vm and 3 stand alone databases version 18.104.22.168.
I need to know if it's possible to upgrade both Grid Infrastructure and databases to version 22.214.171.124. I researched and did no find an answer.
he Oracle Grid Infrastructure/Clusterware (CRS) version must be of the highest version down to the 4th digit in the possible combinations at all times.
This means, you have to upgrade Oracle Grid Infrastructure/Clusterware first.
