Hi, I mined votecoin in an early stage of the coin, i have the VoteCoin 1.0.11 linux client. I tried to export my wallet to import it to the new windows client, but when I try to export i get this message:
./src/votecoin-cli z_exportwallet exporfile
error code: -28
error message:
Verifying blocks...
There is 0 connections for ~35 minutes, so I think i should repair it first? But I do not know how to upgrade step by step, to be able to connect od my linux machine to export the wallet.
Please help me to recover the wallet

I solved the problem
My case was a bit weird, because i mined VOT in 2017 for short time and them moved to another city, leaving my computer, so only version I have had was 1.0.1 cli linux wallet

I couldn't make it to connect to the blockchain, and not every command worked.
I could check my balance(votecoin-cli z_getbalance "address"), but couldn't export wallet(votecoin-cli z_exportwallet "exportfilename"), i was able to run votecoind but it couldn't connect. Moreover, i could make a transaction and chceck it's status(i have it copied, it was successfull). The problem was, the transaction never finished, and in my new windows wallet the transparent address i sent VOT to, has dissapeared. So than I panicked a bit, but it later came to my mind, that if there were no connections, the transaction might be just an illusion

So i tried even harder to export priv key and import it on windows wallet...I googled zcash forums and stepped on this document:
https://en.bitcoin.it/wiki/Original_Bitcoin_client/API_calls_listi used a dumpprivadress to export private addres and restore in in the new wallet on my windows machine, and it worked! The transaction never happened, all the VOT's are in my restored wallet
