12c ASM restart upgrade to 19c
I am preparing the non-prod environment to upgrade to 19c. The current environment consists of 12.1.0.2 ASM single instance restart, 11g, and 12c databases.
There are three disk groups and two of them have database compatibility settings currently set to 10.1.0.0.0, and one as 11.2.0.0.0.
There are multiple databases sharing the same 12.1.0.2 database home. The lowest compatible value for 12c databases is 12.1.0.
There are two 11.2.0.4 databases sharing the same disk groups. The compatible parameter of 11g databases is currently set to 11.2.0.0.0.
Do you find any issues with current settings prior to upgrading the single instance ASM to 19c?
There are no plans of upgrading 11g databases.
