Certain example embodiments of this invention relate to evacuation and sealing techniques for VIG units, and/or multi-chamber vacuum ovens for accomplishing the same. In certain example embodiments, a VIG assembly is inserted into a multi-chamber apparatus to successively reduce the chamber pressure and thus the pressure between substrates comprising the VIG assembly until a final evacuation pressure is reached. Once the final evacuation pressure is reached, a pump-out port or tube of the VIG assembly is sealed forming a VIG unit while the VIG assembly i...
