  Research around cloud computing has largely been dedicated to ad-dressing
technical aspects associated with utilizing cloud services, surveying critical
success factors for the cloud adoption, and opinions about its impact on IT
functions. Nevertheless, the aspect of process models for the cloud migration
has been slow in pace. Several methodologies have been proposed by both
aca-demia and industry for moving legacy applications to the cloud. This paper
pre-sents a criteria-based appraisal of such existing methodologies. The
results of the analysis highlight the strengths and weaknesses of these
methodologies and can be used by cloud service consumers for comparing and
selecting the most appropriate ones that fit specific migration scenarios. The
paper also suggests research opportunities to improve the status quo.
