1. It does not require a full resync. There's a document that explains how to update the wallet:
https://element-hyp.com/cc/how_to_update.pdfQuite simply:
Shutdown your HyperStake wallet if it is running.
Rename the HyperStake appdata folder to Element. And then within the Element appdata folder, delete the following:
db.log, debug.log, governance.dat, peers.dat, and HyperStake.conf
Run the new Element binary. Done.
We're now running a multitude of seed nodes, so addnodes in the .conf are no longer necessary.
But as always, if you have any issues, you can open up a ticket on the HYP Discord server and you can communicate with us directly:
https://discord.gg/TtsmkHHgenok, i've played with it a little.
turned out the only thing that really messed up was "database" subfolder contents, all the rest didn't matter.
