6 Upgrade Vs MigrationUPGRADEThe process of changing the data dictionary contents of a database to reflect a newer releaseNo User or Application data will be touched or modifiedIndependent of the size of the databaseMajor Release Upgrade : Upgrading from 11.2 to 12.1Patchset Upgrade :Upgrading from toMIGRATIONMove to new OS ,hardware and character set conversation.Dependent on the size of the database
15 Install the latest Software Reduce patching downtime:Install the LATEST PATCHSET or BASE RELEASEPatchset is complete installation software from OnwardsInstall the Binaries in new Oracle home . Recommended: OUT OF PLACEApply the latest PATCH SET UPDATE for Unix and BUNDLE PATCH for WindowsThe first PSU for will be released on October 2014Apply Interim Patches for Known issueNote : Quick Reference to Patch Numbers for Database PSU, SPU(CPU), Bundle Patches and Patchsets

23 Time Zone Version Pre or Post Upgrade Actions Default Time Zone Version 12c R1 is DST V18If Time Zone version at source database HIGHER than target databaseApply the Time Zone patch on target to match the source database versionIf Time Zone version at source database LOWER than target databaseTime Zone conversion need to be done post upgrade.Most Recent Time Zone version is DST V22Time Zone definitions in $OH/oracore/zoneinfoNote Scripts to automatically update the RDBMS DST (timezone) version in an 11gR2 or 12cR1 database
24 Backup the DatabaseTake a backup of the Database.Always create a valid and complete online backup with RMANTest the restore and the recovery at least once.Make sure your fallback strategy covers during and after cases
