Downloaded Bitcoin Core and can't find my bitcoin

[Perceptive]

I recently upgraded my bitcoin desktop client from Bitcoin-QT 0.8.6 to Bitcoin Core on Windows. The bitcoin did not show up in the new wallet and I now can't  find my bitcoin and am not able to import my wallet.dat file on Blockchain.info. Is it possible that my wallet.dat file was corrupted? Any help is much appreciated and if I recover my bitcoin will send you some!

Did you backup your wallet?

and I now can't find my bitcoin and am not able to import my wallet.dat file on Blockchain.info. Is it possible that my wallet.dat file was corrupted? Any help is much appreciated and if I recover my bitcoin will send you some!

Whats the errormsg?

Did you try
- walletpassphrase "yourpass" 120
- dumpprivkey "publickey"
in bitcoin core console?

Thanks Shorena. Yes, I do have a wallet.dat file from before I downloaded Bitcoin Core.

There's no error message, the funds just aren't showing up. The error message from Blockchain.info is a 524 error. Is the process you described extracting my private keys?

Also, I uninstalled Bitcoin Core and am now running Bitcoin-QT 0.8.6 again. Does that change how I would go about extracting the private key?

When you say your bitcoin did not show in your wallet do you mean the balance was wrong or that you were missing trasactions?

Do you have your coins now that you have downgraded to 0.8.6?

Also, I uninstalled Bitcoin Core and am now running Bitcoin-QT 0.8.6 again. Does that change how I would go about extracting the private key?

No, it doesn't change it.

I'd try running Bitcoin Core again but with the -rescan option.  (Create a shortcut, right click it, hit properties, and add -rescan to the end of the target field.)

Did you control your addresses on Blockchain.info? If you put your block files to different folder, it could be the problem. Check where you put with -datadir.

There are no transactions. It's like the wallet with funds in it never existed-- the address, private key, and coins are nowhere to be found. Although when I search the address on Blockchain, I see the transactions and funds. The private key extraction does not work (error is: Private key for address 13hZ8DCJ1jQgdgSDZx6DvnGpZbKii11KE9 is not known (code -4))

I'm stuck and pretty disappointed that upgrading to a new bitcoin wallet could cause me to potentially lose a significant amount of bitcoin. Any other suggestions?

I sure hope OP made that transaction. If not, he's never going to see his coins again.

If you have a backup and/or have the private keys, you won't lose the coins.  Shorena made the point above, having a good backup is critical.

However, as was stated below, it looks like you may have resolved the issue since they were moved.

Well either that or he messed the "export the private keys in plaintext"-part up and someone else has the coins now.
He said it didnt work. Which smells like he backed up something else or didnt restore the backup. Either way I hope OP still has the coins.

Thanks so much for all the help guys!

I did in fact access the funds last night and move them after a lot of work. The solution was downloading Pywallet and running a -dumpwallet command which enabled me to dump the keys into a Plaintext JSON WordPad document. I then imported that to my Blockchain.info wallet via their Import Wallet feature. Thankfully, I saved the wallet.dat file before I downloaded Bitcoin Core. Otherwise I'm not sure that would have been possible.

Sounds to me like the wallet.dat that you saved before the upgrade was fine.  You probably could have just recovered that wallet.dat backup into the Bitcoin Core data directory and been fine.  Glad to hear that you recovered your funds, but the pywallet and blockchain.info steps were likely unnecessary.

if I recover my bitcoin will send you some!
