Armed escorts accompanied the women, Doan Thi Huong of Vietnam and Siti Aisyah from Indonesia, as they arrived for their morning court appearance in Kuala Lumpur.
Both smiled at their embassy representatives as they were brought to the dock and wore the same clothes as they did at earlier court appearances.
Their case was formally transferred to the High Court as the lower court had no jurisdiction to hear a murder case.
Prosecutor Iskandar Ahmad said the date for their first appearance in the High Court would usually be within a month.

The two women are accused of smearing VX nerve agent on Kim Jong Nam's face at the Kuala Lumpur airport on Feb. 13. Kim died soon afterward.
The women have said they were duped into thinking they were playing a harmless prank for a hidden-camera show. Yusron Ambary, counsellor at the Indonesian Embassy, said Siti wrote a letter to her parents recently, asking them not to worry about her.
"I am in good health. Just pray. Don't think about me too much. Keep healthy and pray at night. I have a lot of people helping me. The embassy officials always come to see me, my lawyers also. Don't worry. Pray for me so that the case will be over soon and I can go back home. Send my love to my son Rio," he read from the letter to reporters outside the courtroom.
Although Malaysia never directly accused North Korea of carrying out the attack, speculation is rampant that Pyongyang orchestrated a hit on a long-exiled member of its ruling elite. Although Kim was not an obvious political threat, he may have been seen as a potential rival in the country's dynastic dictatorship. Norht Korea has denounced such speculation.
