Blaise 4.8 introduced new features, such as a revised computer-assisted telephone interviewing (CATI) call scheduler, a revamped version of Blaise Internet Services (Blaise IS) and a client/server method of data manipulation and storage. This paper will review the experience of Mathematica Policy Research, Inc. (MPR) in implementing Blaise 4.8 for operational surveys. In addition to the challenges converting from Blaise 4.7 to Blaise 4.8, the conversion enabled us to switch to a new network operating system, which made it possible for us to implement a new internet authentication system and upgrade to new internet and data storage/CATI servers. This conversion to Blaise 4.8 also required us to adjust some of our operational procedures for installing and maintaining instruments in production.
