Hi there, long long time ago, I had created (I don't even remember why) a full node on testnet. Since that's where it consumes electricity and that's it, I would like to pass it on main net. In all honesty, I didn't quite understand how to do it.

Another idea I had, instead of giving the main massage, was to use the data already on the computer, to try to start a Knots node, also in this case, first in testnet and then in main.

The last idea I had was to save the blockchain data somewhere, format the whole server (to clean it from the various attempts made at the time) and then install a new node, but use the data already downloaded.

In short, as you may have understood, I have few ideas and a bit confused, therefore, in addition to help, I also ask for advice.

Thanks in advance to anyone who will help me.
