If some existing processes are running in some other BPM tool and we want to mov

If some existing processes are running in some other BPM tool and we want to move/migrate those processes(not process instances) into Appian. The aim is to choose Appian as the new BPM Platform and to save rework, basically we want to avoid rebuilding all of those processes in Appian. Although the question is very generic but is this possible and to what extent.
Thanks in advance.
