Activities in System Copy Method

Hello all,

We are planning to do a system copy on to one of our DEV system.

We have planned to go with either of these 2 options i.e.

1.To perform a system copy of any QAS / PRD system on to development with / without data to rebuild a new DEV System.

2.To export a copy of the existing DEV, Rebuild a completely new system based on same parameters and import back the DB.

Can anyone explain what are the steps involved in both these steps?

Your suggestion is very much appreciated.

Thanks,

Regards,

Hasan
