Hi Kavitha
In the same you can start target system three steps, Step 1 & 3 you can install one and DB on another systems.
1. SCS & SAP Global host configuration (each steps you have to provide the profiles folder) Host 1
2. DB Import where you are installed the Database -Host 2
3. CI Import on host -1
In this you can use either detach/attach or Backup/restore method.
