FW: Manual UPgrade question

There's a 32MB file of a presentation "Upgrade and Migrate to Oracle Database 11g" by "Roy Swonger & Mike Dietrich".

Search for it on oracle's site (or a google search).  

Also remember that behaviour of Group By changes (results are NOT ordered as you might have expected / seen them in 9i - so an ORDER BY is necessary if you expected sorted results), many optimizer changes as well. Changes to dbms_stats are also significant.

Specifically responding to :  

According to documentation, the datafiles are not changed. The upgrade involves recompilation of binaries and such.  

Or does the upgrade alter the contents of the sys tablespace?

The Upgrade *DOES* update the system tablespace (lots and lots of changes !). It would update the UNDO Tablespace. It also needs a new SYSAUX tablespace. Datafile headers need to be updated when the database is OPENed.  

The word size conversion requires additional scripts --- utlirp.sql and utlrp.sql and a separate script for Java objects.

There are a number of support notes on word size conversion --- 62290.1, 548978.1, 341880.1 are three that I have saved.

Subject: Manual UPgrade question                   

So working on a manual upgrade of 9iR2 to 11gR2. Changing hardware and word size. Import/Export is not an option, DBUA is not an option, nor is transportable tablespaces. Manual is all I have left short of buying migration software such as Shareplex or Goldengate.  

The manual upgrade appears straight forward. My question is for after the upgrade.  

So I have a new server that will be my production server. I'll do my testing on it. So, assuming the manual upgrade is successfully wrung out and tested and I'm ready to do the live upgrade.  

I'm curious if , now that I have the upgraded DB on the production server could I just recopy over new versions of the datafiles, controlfiles, redo Logs(?) and restart the upgraded database without having to run through the upgrade again.  

According to documentation, the datafiles are not changed. The upgrade involves recompilation of binaries and such.  

Or does the upgrade alter the contents of the sys tablespace?  

Thanks
