Hi Shaik
Below are some of the action items
1. You have to import all the IR objects from Dev. Create separate transport request for each s/w component.
2. Create the business system for preprod in SLD , then map the same as a target buisness system in SLD.
3. Import the integration directory objects.Then update the communication channels with appropriate connection parameters.
4. Maintain value mappings in ID.
Thanks,
