ICO Transport vs iFlow Transport

Hello PO Minds,

This is my first time transporting Objects from PO DEV to QA. I am thrilled & confused to see so many blogs about moving transports with iFlows & not many blogs or comments saying the same can be carried out by transporting ICO's from the Swing environment.

I am beginning to wonder if there is a standard practice & why !

Is moving ICO's to QA & generating iFlow for them advisable.. or moving iFlows to QA & deploying them to generate an ICO is advisable !

Would these methods of transport have any effect on our scenario in the production ?!

In otherwords, is any one of these transport method more production friendly than the other ?

I know its not a great question but Id like to know the difference & the reason if there is any.

Thanks & Regards

Sam
