Client Export/Import

Hi Team,

we have two ERP 6.0 System, both the system have different-2 Database , One system having Oracle 11 G  database and second system having SQL Database.

Now i want to confirm is it possible client export from Oracle database and import into the SQL base system ?

or is it another way because in target system two client is already there , we want to create new client and import client dependent data only ?

Thanks is advance . your input is highly valuable.
