    Good document or link on how to Upgrade Oracle 10gR2 RAC to 11g R2 RAC On HPUX 11.31i

      Hello All,

       

      Am looking out for a good document/link which lists all step by step how to upgrade Oracle 10gR2 RAC to 11g R2 RAC On HPUX 11.31i.

       

      Operating System – HP-Unix 11.31i


      Source Oracle Database Version – 10.2.0.5.5  (Oracle 10g Release 10.2.0.1.0  upgraded with Oracle Database 10g Release 2 Patchset 4)

      Target Oracle Database Version – 11.2.0.4 

       

      ASM used in Source environment. The OS and Server remain same throughout the Upgrade.

       

      Should I use a swing gear - additional server to host the DB on when upgrade is on

      Or,

      Take database/OCR/Voting Disks Backups and then directly upgrade the Oracle Clusterware to Grid-Infrastructure including both Oracle and Grid homes in "rolling upgrade" approach?

       

       

      I think the second approach is much better as that will minimize the downtime needed.

       

      A detailed link to a detailed "step by step" document will be highly appreciated.

       

      Many Thanks,
