Hi Erman,
 

Existing environment:

Operating System RHEL 5.5 32-bit

Oracle Database 11.1.0.7 32-bit

Oracle Apps version 12.1.3 32-bit

Single node environment where database and apps hosted on the same server.

 

Requirement is to migrate 32-bit environment to 64-bit. As per our understanding, In outline:

 

Since RHEL Linux 5.5 -32 bit is not certified with any one of the EBS database and to be in valid certified configuration, we need to upgrade the OS version from RHEL 5.5 to RHEL -6 32-bit for to certify the database of version 11.2.0.4
 

DB will be upgraded from 11.1.0.7 to 11.2.0.4 which is certified with RHEL 6 32-bit.
 

Once database is upgraded, we will install RHEL 6 32-bit on new server.
 

We will Clone apps and database to the new server after meeting all the prerequisites in both Source and Target.(471566.1)
 

Then we will do actual OS 32 bit to 64-bit migration.
 

Please let us know if there is any change in above steps.

 

Thanks,

Satish
