<p>I am trying to import the balance from the older version to the newer one. I deleted the wallet.dat from the newer one and copied the older one into its place. However, the wallet will not start with the old wallet.dat. I get a small "error" msg box. When I click "ok" qt closes down. </p>

<p>Are the two wallets incompatible? If so, is there another way to import my balance to the new wallet?</p>

<p>Thanks</p>

What does the error message box say?

Its a very small box that says "Bitcoin" in the title bar, then it has a red circle with a white x in the box with an "ok button underneath. When I click the "ok" button, qt shuts down. If I do nothing, qt freezes (behind the box) with "verifying wallet..." printed at the bottom.

The strange thing is that this wallet.dat that I can not open in another instance of qt, works just fine in the original qt client it came from.

# How to copy wallet.dat from v0.10.2.0 to v0.11.0.

(Asked by: username_0 on 2016-03-22)

I am trying to import the balance from the older version to the newer one. I deleted the wallet.dat from the newer one and copied the older one into its place. However, the wallet will not start with the old wallet.dat. I get a small "error" msg box. When I click "ok" qt closes down.

Are the two wallets incompatible? If so, is there another way to import my balance to the new wallet?

Thanks
