I made sure siad wasn't running and then I copied and backed up to my desktop the wallet folder from inside the sia folder (old version).
I opened the new sia version and let it update. I then closed it and quit siad. Then I pasted the wallet folder from my desktop to my home folder and deleted the new wallet folder. I opened the updated sia but it says I have 0 coins. What did I do wrong?
What I did is that after running the new version for a little bit, I replaced the wallet.dat with the old wallet.dat in both client folder and home folder. I also replaced the database (I think it is called chain.xx in the client folder) with the old one. Then I restarted the client. As soon as the blockchain was updated I saw my coins showed up.
