Datapump command like impdp can be used for importing the 10g DB contents into the 11g DB.

Update:

The above datapump command is an example of logical backup which can be done when a database is in running mode. Below are the common steps followed during a logical backup and restore:

  1. Export(Backup) of full DB is taken in old server:

    expdp system/password@db10g full=Y directory=DIRECTORY_ON_SERVER dumpfile=DUMPFILE_NAME.dmp logfile=LOGFILE_NAME.log

  2. Dumpfile moved to new server

  3. Import(Restore) dumpfile in the new server:

    impdp system/password@db11g full=Y directory=DIRECTORY_ON_SERVER dumpfile=DUMPFILE_NAME.dmp logfile=LOGFILE_NAME.log

More details on this can be found in --> https://oracle-base.com/articles/10g/oracle-data-pump-10g (Better than Oracle docs)

Now coming back to the actual question, what you are asking is a restore of the cold backup in 11g DB server.

The restore of the cold backup can be done by using RMAN command(s) as below:

RMAN> restore database from TAG='COLD_BACKUP_FILE_NAME'

I assume that you have taken backup of all the necessary files during the cold backup process.

Hope this helps you !!
