Whether Cold backup method can be used to "migrate oracle DB"?
Can cold backup can be used to create replica/ DB migration?


Yes of course


  If i tried above process , shall i am able to start the db on target
  server without any errors ?


If you had cloned the machine or installed Oracle binaries in destination machine, only you need another steps:


Copy passwords file for your database, file $ORACLE_HOME/dbs/orapwSID
Copy line of /etc/oratab describing the database you are cloning into
destination machine.



  As i don't have any archive logs, will that create any problem here?


Yes its a cold backup, you don't need archivelog for nothing.
