The easiest way to perform this operation is to copy a cold backup of this database to the new server. On the new server, create an empty database with the same DBID. Shutdown this empty database. Copy the control files, online redo logs and database datafiles from a cold backup to the new server. If you use the same directory structure, then you will be able to start your clone database without problems. If the directory structure changes, you may need to start the database in MOUNT mode and rename the files.
