I have DMA data in G', G'' and shear strain. Getting E' and E'' should be straight forward with G = E/2(1+v). But how to get the elongation strain in a way that MCalibration can use it as DMA data? 

When I transform shear data to principal stress/strain I get a both tension and compression. So I have a more complex loading than what MCalibartion is asking for. How should I use my shear DMA data in MCalibration?

If I understand your question correctly, you have G' and G'' data, and you want to find a material model using MCalibration. If that is the case, then you do NOT need to convert it to E' and E''. Instead, in MCalibration just specify that you have shear data:
