Both the IGES (.igs, .iges) and Parasolid (.x_t, .x_b) CAD formats are well supported in modern 3D/CAD software, so you shouldn't have trouble in find a program or converter that can perform igs to x_t conversion. Used to transfer CAD designs or models from one platform to another.

Convert from iges file format
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned iges to x_t. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
