We may need to upgrade database timezone file during database upgrade from 11g to 19c. Below recommend action is from preupgrade.jar information tool.
Upgrade the database time zone file using the DBMS_DST package.
The database is using time zone file version 14 and the target 19 release ships with time zone file version 32.
Oracle recommends upgrading to the desired (latest) version of the time zone file. For more information, refer to "Upgrading the Time Zone File and Timestamp with Time Zone Data" in the 19 Oracle Database Globalization Support Guide.Below are the steps to Upgrade the database timezone file
Connect to sqlplus and start the database in upgrade mode
sqlplus / as sysdba
shutdown immediate;
startup upgrade;
Check the current timezone file version
SELECT * FROM v$timezone_file;
--output:
SQL> SELECT * FROM v$timezone_file;

BEGIN
l_tz_version := DBMS_DST.get_latest_timezone_version;
DBMS_OUTPUT.put_line('l_tz_version=' || l_tz_version);
DBMS_DST.begin_upgrade(l_tz_version);
END;
