Converting from Single-Instance Oracle Database to Oracle Real Application Clusters
You can convert from Oracle Database 19c single-instance databases to Oracle
RAC using Oracle Database Configuration Assistant, rconfig
, or Oracle
Enterprise Manager.
For an in-place conversion, you cannot change the Oracle Home User. For an out-of-place conversion, you can change the Oracle Home User only if the Oracle home for the single-instance database is not already configured with a Windows Domain User Account.
