BIAR file

Hello gurus,

I would like to know as how to create the BIAR files. I went through the forum but could not get the solution. Even in import wizard pdf does not have the information on how to build BIAR files.

And is using Import wizard easy? I have to import a modified universe and a report built on that universe to production.

Please lt me know which is the best practice to move universe from one environment to another env, is it:

1. Source = Dev environment and destination = Prod env

or

2. source = Dev to BIAR file and from biar to production.

Thanks,

Naveen
