Hi, you will follow -> Migrating Oracle E-Business Suite R12 from Linux 32-bit to Linux 64-bit (Doc ID 471566.1)


11.1.0.7 is not certified with RHEL 6, but 11.2.0.4 is certified with RHEL 5 32bit & 64 bit.

If the requirement is just migrating 32-bit environment to 64-bit, then it seems you can do it already..
But using 11.1.0.7 is not a good idea.. You should use 19C.. So you should upgrade to 11.2.0.4 and then you should consider upgrading 19C.

Note that, 19C requires Linux 7..

There are 2 ways;

If you want to upgrade your database during this process, then you can upgrade it in place (so upgrade 11.2.0.4 while you are using RHEL5), then you
can migrate to 64 bit (to Redhat 7 or Oracle Linux 7) -- (but this move is a little tricky because it involves both migration + OS upgrade) and then do the 19C upgrade..

or

As you say; migrate to Redhat 5 64 bit. Upgrade your database to 11.2.0.4 there and then migrate your database to Redhat 7 64 bit and upgrade your database to 19C while you are on Redhat 7 64bit :) this is also a good plan.. I feel myself closer to this one..
