What happens to PASSWORD_VERSIONS during an upgrade to Oracle 12.2?

I did blog a day ago about ORA-1017 connection issues in Oracle Database 12.2 once you would like to use the deprecated init.ora/spfile parameter SEC_CASE_SENSITIVE_LOGON=FALSE:

But how can this change actually happen?

Let’s check how the PASSWORD_VERSIONS is set in a fresh Oracle Database 12.1.0.2 database with the January 2017 Proactive Bundle Patch applied to it:

SQL> select username, password_versions from dba_users order by 1;

USERNAME		       PASSWORD_VERSIONS

APPQOSSYS		       10G 11G 12C
AUDSYS			       10G 11G 12C
DBSNMP			       10G 11G 12C

GSMCATUSER		       10G

Recently a customer asked me if we’d changed the behavior of this parameter in Oracle Database 12c Release 2 as he receives now an ORA-1017: Invalid username or password error when …
