Training Z systems

I have two questions:
1) I am runing live on a small cloud server, and have Zorro S. As described in the manual, I can stop trading, but not close, retraain, and resume trading. However, since my server is very small, it is painfully slow to train. If I train on another machine, do I just copy over the .par files when pause the live trading Zorro?

2) I have started live trading a week ago with ver 2.25. Is it recommended to retrain since it has been ~3 months since 2.25 release?

Thanks

Generally it is not recommended to retrain the Z-Systems.
I personally would never attempt it with Z7.

Why not just wait another month for the new version?

Technically, you can train on the other machine and overwrite .par & .fac
Trades could be left open.

Thanks. I was actually thinking of waiting for the next release. I wanted to know if I could train on the other machine and copy over the .par & .fac files.

Thanks again.

Important on that, don't change the trained script vs. live script.
They have to be of course 100% identical.
