Tsx Nano program conversion

Hi,
I would like to ask if anyone has had any experience on converting an old PL7-07 program for a Tsx Nano plc, to a program suitable for e.g. Schneider M340 PLC or equivalent? Schneider has informed me that the Ecostructure Control Expert is the software needed to do this, and also provided me with this link : https://www.se.com/in/en/faqs/FA289143/
However, the article in this link describes a process relating to the PL7 software, which I believe cannot be used with Tsx Nano at all. Hence this question; is it possible in any way to convert the old PL7-07 program, or is rewriting it the only solution?
Thank you
