How to change the diskgroup attribute "compatible.rdbms" safely

We have five production databases on a 2-node RAC cluster with ASM, and we would like to change the diskgroup compatibility attribute "compatible.rdbms" from 10.1 to 19.0

These are the current values :


SQL> SELECT SUBSTR(dg.name,1,12) AS diskgroup, SUBSTR(a.name,1,24) AS name, SUBSTR(a.value,1,24) AS value, read_only FROM V$ASM_DISKGROUP dg,V$ASM_ATTRIBUTE a WHERE dg.group_number = a.group_number AND a.name LIKE 'compatible%';

DISKGROUP  NAME           VALUE          READ_ON

------------ ------------------------ ------------------------ -------

CRSDG    compatible.asm      19.0.0.0.0        N    

CRSDG    compatible.rdbms     10.1.0.0.0        N    

CRSDG    compatible.advm     19.0.0.0.0        N    

DATADG    compatible.asm      19.0.0.0.0        N    

DATADG    compatible.rdbms     10.1.0.0.0        N    

Howdy, Stranger!
