Facts:

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

In option 1 we said;

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.

->-----------
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..
->-----------

So, you can upgrade your db in-place and then convert to 64 it (by installing a rhel 5 64 bit and doing the migration) .. Then! You should install Linux 7 64 bit and migrate to there and lastly upgrade your db to 19C .. Linux 7 is required for 19C.
