During development and tumour metastasis, groups of cells can migrate together. Using border cell migration in Drosophila as a model, Rorth et al. show that cells move in two distinct phases by different mechanisms. To mediate these movements, information processing of signalling pathways occurs at the single-cell and the multicellular level.
