Here is a demo of moving a partition of the BALANCES table in the BALANCES schema to a separate Schema (ARCH), Tablespace (ARCHIVAL) and Table (BALANCES_ARCH).
SQL> connect hemant/hemantThe account HEMANT is the DBA account. BALANCES owns the Source BALANCES table in the BALANCES Tablespace. ARCH owns the the Archival BALANCES_ARCH table in the ARCHIVAL Tablespace.
