Upgrade Vs Migration UPGRADE The process of changing the data dictionary contents of a database to reflect a newer release No User or Application data will be touched or modified Independent of the size of the database Major Release Upgrade : Upgrading from 11.2 to 12.1 Patchset Upgrade :Upgrading from 12.1.0.1 to 12.1.0.2 MIGRATION Move to new OS ,hardware and character set conversation. Dependent on the size of the database

Remove Obsolete Components Enterprise Manager Database Control Repository is superseded in 12c By EM Express Remove EM repository It will be automatically removed during the catuppst.sql post-upgrade phase. $emctl stop dbcontrol SQL> @ ?/rdbms/admin/emremove.sql Remove Oracle UltraSearch before doing the upgrade Oracle UltraSearch does not exist in Oracle Database 11.2 and onwards For Oracle Database 10.2 SQL> @ ?/ultraserach/admin/wk0deinst.sql SYS password ‘‘ ‘‘

Processes the audit records to minimize downtime. Move records to an interim temporary table.

Time Zone Version Pre or Post Upgrade Actions Default Time Zone Version 12c R1 is DST V18 If Time Zone version at source database HIGHER than target database Apply the Time Zone patch on target to match the source database version If Time Zone version at source database LOWER than target database Time Zone conversion need to be done post upgrade. Most Recent Time Zone version is DST V22 Time Zone definitions in $OH/oracore/zoneinfo Note 1585343.1 Scripts to automatically update the RDBMS DST (timezone) version in an 11gR2 or 12cR1 database

Backup the Database Take a backup of the Database. Always create a valid and complete online backup with RMAN Test the restore and the recovery at least once. Make sure your fallback strategy covers during and after cases

Compatible Parameter Compatible 11.0.0 or higher is MUST Minimum COMPATIBLE parameter for 12c is 11.0.0. Leave COMPATIBLE at the original value for a week before changing to 12.0.0. No way back once COMPATIBLE set to 12.0.0 Compatible 11.0.0 or higher is MUST Downgrade NOT possible Compatible remain to 11.x.x Downgrade possible Database restart is required to change the COMPATIBLE parameter later SQL> alter system set compatible = '12.0.0' scope=spfile; SQL> Shutdown immediate ; SQL> conn / as sysdba SQL> startup
