gnucash how to switch commodity from ROL to RON?

[vaida bogdan]

I'm facing a little problem using gnucash:

Romania is in the process of switching from ROL to RON commodity. 1
RON = 10000 ROL. There are 2 problems I'm facing:

1.

RON doesn't exist yet in the commodity list. When will it be added?

2.

All my money in gnucash shows in ROL and now I have to switch it to
RON.  How do I do that?

Please cc me the answer as I'm not subscribed to this list.

Thanks in advance,
