A case study, which demonstrates methodological approaches to sensible migration from traditional methods of data collection, such as face-to-face to online. Data analysis from a JDPAP syndicated study, using a large robust face-to-face sample, demonstrated how the internet connected sub-sample can be used to weight and calibrate the internet sample in any Asian country, to be representative and valid. This paper investigates how adoption of internet methodology might impact on results and consistency in data outputs, and how to scientifically manage this migration. The paper addresses one of the key challenges facing developing markets that might not have high internet penetration, and the experiences of managing and ensuring data collection quality, using the internet. The comparison of the internet connected sub-sample, with the total sample interviewed face-to-face is akin to conducting parallel research. Differences in data output for the two samples are presented, and weighting strategies necessary to calibrate the internet sample, and build a bridge between methodologies, provide many insights for migration to online in Asia.
