Well have you sent any bitcoin transaction from the old wallet to the new one?
If you haven't, and you lost all the copies of the old wallet.dat, I'm afraid you lost access to the bitcoins (especially if the wallet copies were deleted a long time ago).
I just know that looks like the same file i keep on my cellphone micro sd from the last time i see the bitcoin. I know that wallet.file is the old one. I remember i encrypted with the password i got. It was a bunch of addresses and private keys. now to complete the wallet.dat file change for a notepad symbol and yes i make 2 transaction from the wallet and then instead of 4,005 encryoted keys got 4011 encrypted keys. The wallet add ^ keys more for those transactions. How i got 4,011 transactions now? the wallet added the transaction with the old ones.
Do you see the pics showing the before and after the transactions?
