You can migrate from server to other server too using this tutorial.
1. create TNS on the new server, locate in dir $ORACLE_HOME/network/admin
2. open firewall host
3. create DBCA, locate in dir $ORACLE_HOME/assistants/dbca/ with name dbcaICNPRODB.rsp.
4. create tablespace
5. export database, make sure you have directories oracle for location export file
and then follow this command
expdp username/password@your_database reuse_dumpfiles=y schemas=your_schema dumpfile=expdp_yourchema.dmp directory=EXPDP_BKP_ICNPRODB logfile=expdp_your_schema.log
you will see the export progress
then transfer export file to destination server with this command
scp expdp_your_schema.dmp
oracle@your_ip_destination:/home/oracle
6. import database *login into destination server
import database with this command
impdp user/pass directory=DATA_PUMP_DIR dumpfile=expdp_your_schema.dmp logfile=expdp_log_5102019.log
the import progress is running, wait until success
