Creating a replica of Informatica and DAC..

Question

Hi Experts,
We just have one environment containing DAC and Informatica. ( call it prod)
Now we are planning to create a DEV environment containing exactly the same DAC and Informatica metadata.
I think having the DAC repository and Informatica repository to the new environment would do the trick.
Can anyone guide me as to how to create  exactly  the same replica of the running DAC and informatica environment?
Thanks
Ashish

Hi Ashish,
In addition to Naga's post:
If you need start your ETL processes on DEV enviroment as Incremental, you need to clone Prod DWH.
If your DWH, DAC, Informatica are on the same instance,you can clone whole instance and then replace DAC and Informatica Metadata by Importing repository wizards.
Remember that you need set correct relational connections in Informatica and several changes on DAC Setup (as Informatica Servers , Physical Data Sources,...)
The very important point is the chronological snapshots of OLTP,  DAC Metadata, Informatica Metadata and DWH.
1 -  DWH, 2 - Informatica, 3 - DAC  , 4 - OLTP  (for example DWH 1-JAN, Informatica 2-JAN, DAC- 3-JAN, OLTP - 4-JAN).
The reasons is correct corresponding between source,  sequences on Informatica Maps and  ROW_WID  fields of DWH tables.
