If you are using the OPS$ mechanism then follow the SAP note 50088 - Creating OPS$ users on Windows NT/Oracle and run the script attached. The script wont drop the source system OPS$ users, instead you need to do them manually.
If you are using the SSFS mechanism these check this SAP note 1639578 - SSFS as password storage for primary database connect
You will need to recreate the PSAPTEMP tablespace.
Eg: ALTER TABLESPACE PSAPTEMP ADD TEMPFILE '/oracle/SID/sapdata1/temp_1/temp.data1' SIZE 10000M REUSE AUTOEXTEND OFF;
Start the Oracle listener and switch to sidadm user and run R3trans -d. You should get RC 0000.
If OK then continue with the post operations like SAP License installation, TMS, BDLS and the rest.
