OBIEE 11g to 12c Upgrade with platform change from 32bit to 64bit.

Is it possible to upgrade from OBIEE 11g 32bit to 12c 64bit ?

Should we migrate first to the 64bit 11g installation and then do a migration to 12c?

Haven't tried it but I think you can migrate directly from OBIEE 11g 32 bit to OBIEE 12c 64 bit as migration jar file just bundles togather OBIEE artifacts(RPD,Catalog and Security) along with configuration files(instanceconfig.xml,NQSConfig.INI etc..) and it doesn't bundle any of the library files from one system to another.

And as far as bi-migration-tool.jar file generated on 64bit OBIEE 12c system execution on a 32 bit OBIEE 11g system is concerned, it does not make any difference to have a jar compiled with 32-bit or 64-bit. It should be machine-independent, unless we have some native library dependency or the java code is directly being compiled to native code.

But if you face any of the non reported issue before, then be ready to migrate your OBIEE 11g to 64 bit and then perform the migration again.

I don't see any issue because even if the JAR collecting your metadata (RPD + catalog + security) wouldn't work you can still move the elements directly and migrating them on your 12c like the JAR would do. So you definitely don't have any link with the 32 or 64bit of your OS.

Thank you for your quick response.

I found the following manual.

-----------------

■Upgrading Oracle Business Intelligence12c (12.2.1.2)

https://docs.oracle.com/middleware/12212/lcm/OBIUP/OBIUP.pdf

2.4.2.1 Migrating from a 32-Bit to a 64-Bit Operating System

If you have a 32–bit operating system, then you must migrate your 32-bit environment

to a 64-bit software environment before you upgrade.

Make sure to validate the migration to ensure all your Oracle Fusion Middleware 11g

software is working properly on the 64-bit machine, and only then perform the

upgrade to Oracle Fusion Middleware 12c.

I think I had better follow the instructions in the manual...

Yeah that's always better follow the product guide and please close this thread.

Just for the records (and for the users looking for an answer in the thread): the correct answer is more the piece of doc @2715862 posted because "RTFM" is always a right answer
