2. Perform the Upgrade Prechecks:

One of the best recommendation to create GRP before proceeding with DB upgrade:

Run preupgrade.jar

Download the latest "preupgrade.jar" file from MOS 884522.1. If you don't have MOS access you can miss out the next step.

==============
BEFORE UPGRADE
==============
  REQUIRED ACTIONS
  ================
  1.  Set DB_RECOVERY_FILE_DEST_SIZE initialization parameter to at least 9326
      MB.  Check alert log during the upgrade to ensure there is remaining free
      space available in the recovery area.
      DB_RECOVERY_FILE_DEST_SIZE is set at 8016 MB.  There is currently 5926 MB
      of free space remaining, which may not be adequate for the upgrade.
      Currently:
       Fast recovery area :  /u01/app/oracle/fast_recovery_area/DB12C
       Limit              :  8016 MB
       Used               :  2090 MB
       Available          :  5926 MB
      The database has archivelog and flashback enabled, and the upgrade
      process will need free space to generate archived and flashback logs to
      the recovery area specified by initialization parameter
      DB_RECOVERY_FILE_DEST.  The logs generated must not overflow the limit
      set by DB_RECOVERY_FILE_DEST_SIZE, as that can cause the upgrade to not
      proceed.
  RECOMMENDED ACTIONS
  ===================
  2.  (AUTOFIXUP) Gather stale data dictionary statistics prior to database
      upgrade in off-peak time using:
        EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;
      Dictionary statistics do not exist or are stale (not up-to-date).
      Dictionary statistics help the Oracle optimizer find efficient SQL
      execution plans and are essential for proper upgrade timing. Oracle
      recommends gathering dictionary statistics in the last 24 hours before
      database upgrade.
      For information on managing optimizer statistics, refer to the 12.2.0.1
      Oracle Database SQL Tuning Guide.
  INFORMATION ONLY
  ================
  3.  To help you keep track of your tablespace allocations, the following
      AUTOEXTEND tablespaces are expected to successfully EXTEND during the
      upgrade process.
                                                 Min Size
      Tablespace                        Size     For Upgrade
      ----------                     ----------  -----------
      SYSTEM                             840 MB       947 MB
      TEMP                                20 MB       150 MB
      UNDOTBS1                           155 MB       439 MB
      Minimum tablespace sizes for upgrade are estimates.
  4.  Check the Oracle Backup and Recovery User's Guide for information on how
      to manage an RMAN recovery catalog schema.
      If you are using a version of the recovery catalog schema that is older
      than that required by the RMAN client version, then you must upgrade the
      catalog schema.
      It is good practice to have the catalog schema the same or higher version
      than the RMAN client version you are using.
  ORACLE GENERATED FIXUP SCRIPT
  =============================
  All of the issues in database DB12C
  which are identified above as BEFORE UPGRADE "(AUTOFIXUP)" can be resolved by
  executing the following
    SQL>@/u01/app/oracle/cfgtoollogs/DB12C/preupgrade/preupgrade_fixups.sql
=============
AFTER UPGRADE
=============
  REQUIRED ACTIONS
  ================
  None
  RECOMMENDED ACTIONS
  ===================
  5.  Upgrade the database time zone file using the DBMS_DST package.
      The database is using time zone file version 26 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.
  6.  (AUTOFIXUP) Gather dictionary statistics after the upgrade using the
      command:
        EXECUTE DBMS_STATS.GATHER_DICTIONARY_STATS;
      Oracle recommends gathering dictionary statistics after upgrade.
      Dictionary statistics provide essential information to the Oracle
      optimizer to help it find efficient SQL execution plans. After a database
      upgrade, statistics need to be re-gathered as there can now be tables
      that have significantly changed during the upgrade or new tables that do
      not have statistics gathered yet.
  7.  Gather statistics on fixed objects after the upgrade and when there is a
      representative workload on the system using the command:
        EXECUTE DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;
      This recommendation is given for all preupgrade runs.
      Fixed object statistics provide essential information to the Oracle
      optimizer to help it find efficient SQL execution plans.  Those
      statistics are specific to the Oracle Database release that generates
      them, and can be stale upon database upgrade.
      For information on managing optimizer statistics, refer to the 12.2.0.1
      Oracle Database SQL Tuning Guide.
  ORACLE GENERATED FIXUP SCRIPT
  =============================
  All of the issues in database DB12C
  which are identified above as AFTER UPGRADE "(AUTOFIXUP)" can be resolved by
  executing the following
    SQL>@/u01/app/oracle/cfgtoollogs/DB12C/preupgrade/postupgrade_fixups.sql

Execute fixup scripts as indicated below:
Before upgrade:
Log into the database and execute the preupgrade fixups
@/u01/app/oracle/cfgtoollogs/DB12C/preupgrade/preupgrade_fixups.sql
After the upgrade:
Log into the database and execute the postupgrade fixups
