Is any functional changes required for EBS upgrade from 12.1.2 to 12.2.9

[soumya]

Hi Erman,

As mentioned in my earlier post http://erman-arslan-s-oracle-forum.2340467.n4.nabble.com/EBS-upgrade-12-1-2-to-12-2-9-and-DB-upgrade-to-19c-td9032.html


Does this kind of upgrade specially from 12.1.2 to 12.2.9 incur any major functional changes  for any module in EBS?

Thanks,
Soumya
