 Hi Experts,

I need some advice on the following.

We at our organisation are in process of Upgrading our 11.5.10.2 EBS to 12.1.3 & also migrating from 32 bit to 64 bit. Now in order to achieve this we can go with any 1 of the below 2 approaches

1) Migrating 11.5.10.2 from old to new Hardware with 64 bit OS & then Upgrading to 12.1.3.

2) Upgrading  11.5.10.2 to 12.1.3 on existing 32 bit environment & then migrating to new 64 bit.

Please advice on which aproach would be best keeping in mind that 11.5.10.2 is only supported with spilt configuration for 32 to 64bit migration where as R12 is supported for both db & apps.

I would like to know what are the benefits of migrating oracle EBS from 32bit to 64bit, would their be any significant performance gain if yes in which areas.
