Custom top - R12.2 upgrade

[satish]

Hi Erman,

We are in process of upgrading R12.1.3 to R12.2
We have an existing custom application xxsss

Do we need to deregister custom application before upgrading to R12.2?

Thanks,
Satish

No you don't deregister them.

Is there a document and note that made you think about this?
