2. Take controlfile trace and pfile or spfile (that was using by the source database)

3. Install Oracle software on another machine (choose “Install only” option in OUI). Don’t create any database

4. Copy all the files (including trace file and pfile or spfile) from source server to target server either using FTP or rcp

5. Place pfile or spfile in “dbs” directory on target

6. Copy the remaining files to their respective locations (If any directories are missing, do create them)
