Question is what is best way to do this ?

I surfed & found that oracle SQL Developer can help check this Link

Does this will work ?? Or I have to fallow RMAN cloning option ?

What is best suitable way for doing this ?

    I wouldn't use our Database Copy for this - that's more for ad hoc copies. If you want to migrate/consolidate entire instances, there are much more efficient ways.

    expdp and impdp are probably a lot more efficient than using SQL Developer for this. If you can create a DBLink you don't even need intermediate files for that

    Yep!! I am thinking exdp & impdp too. I am exploring all possible ways as db is not live & I am just running tests. @a_horse_with_no_name : I used DB links for vertical & horizontal fragmentation, who it can help in migrations ?

why do you need windows at all? you even do not need sql developer.

  • shutdown the source database
  • scp datafiles(.dbf .ctl)
  • scp files in ORACLE_HOME/dbs (like initSID.ora, spfileSID.ora, and also password file)
  • you should also create dirs for diagnostic_dest (where alert.log is placed)
  • amend /etc/oratab
  • set the right SID
  • start the database

PS: this assumes that the Oracle version (including fixpack) is exactly the same.

As time goes on, this answer changes.

Current answer should involve a move to a Multi-Tenant setup. The latest version (19c, soon 20c) allows 3 Plugable Databases (PDB) without a license.

Licensing Information for 19c:

For all offerings, if you are not licensed for Oracle Multitenant, then you may have up to 3 user-created PDBs in a given container database at any time.
