Update from the team of XSH
XSH have just recently passed block #790,000, and the fork block #800,000 is coming very soon!
In preparation for the fork, we recommend all users to simply keep their v2 wallets closed. Please keep your wallet.dat file backed up (in multiple places if possible), and await further instructions (which will be given after the fork, and after its stability has been verified).
There is a possibility that if you keep your wallets open, you would receive blocks past #800,000, but they will be invalid on the main chain (pools and exchanges have received a supplementary wallet update to prevent this).
Due to the vast differences in v2.x and v3.x and the integration of years of updates to Bitcoin Core, we are taking this approach to make the transition as clean as possible, by minimising interference with the old wallet code.
Thank you!
Thanks for the info.
I have a question,sorry but I'm not so confident with forks and I don't want to lose my XSH

So,we have passed block 793417 now,I have the QT desktop wallet,I exported in *.dat format my wallet data.
As far as I understood all,i have to keep closed my V2 QT wallet,waiting for the V3 then import *.DAT file onto new v3 wallet?
Thanks
Ale
