Yes, There is multiple ways to import process maps into ARIS, using standard XML import, BPMN import, or for special cases, custome reports can be designed to import data from external data sources (json, csv, visio, jdbc)
@Evgeny Belenky you can import it.
You can export BPMN (or XML) files from iGrafx, and then import them using BPMN import in ARIS.
Note, sometimes you need to modify the BPMN script in ARIS to override some import errors.
