Upgrade from Syscoin 3 to Syscoin 4

Hi, I have just upgraded my SYSCOIN 3 to SYSCOIN 4 using QT3 and QT4.

I followed the guide here: Syscoin 3 to Syscoin 4 Upgrade Instructions | by Syscoin | Medium

I went onto QT3, used my old data directory and managed to see my old wallet receiving address on the SyscoinQT which was this - Trezor Syscoin Explorer

My aim is to recover the SYS inside it (6.813 SYS).

So I dumped the wallet and imported it onto QT4.
After importing it, I see that the new wallet has included that old wallet address too.
But the balance does not show my 6.813 SYS.

Did I do anything wrong?

Probably not.
Here are a few things you can try:

  1. check on an explorer if the addresses in question actually hold sys https://sys1.bcfn.ca/
    1.a. If not, the coins aren’t there, you might have moved them in the meantime (if that happened on the sys 4 chain, the explorer will tell you), it might be the wrong wallet.dat. In any case you’ll have to find other keys to get access to the coins
    2.b. If the explorer shows your coins, but the 4.2 client does not, this means it’s not synced properly. You can reindex and rescan the blockchain. If you have any questions regarding this, just ask.

Yeah I’ve already checked that it holds the sys.

I’ve done rescanning too already.

That is indeed strange. I’ve forwarded it to the team.

Can you try: running getaddressinfo SWS2hMm4gagZgBvLAAzgWdsnjgAs2qgccM in the console and post the output?

I’m currently running the reindexing.
But here’s the output.

Hey, after reindexing the blocks, I gotten the transaction now!

Thanks for the prompt replies and help! @einalex
