Worked. Thanks so much for all the help.

What are the reasons I would chose an import over a sweep? (another poster suggested sweep is better)
 

(edited to add steps)

Thanks for the response.  The video is a bit different than current version of Electrum.  Can I get a bit of assistance on the exact procedure for a sweep?

1. extracted private key from multibit  (have address as well)
2. Opened up Electrum. Typed default wallet name the press next.
3.selected standard wallet then next
4. Selected create new seed then next
5. Selected standard seed type then next
6. Saved seed words then next
7. Retyped seed words then next
8. created wallet password then next
(wallet created)
9. From menu select  wallet >Private keys > sweep
10. Screen is open where its asking me for two things. "Enter private keys" and address.

Is this where I put the private key I extracted from multibit and the prior wallet address from multibit? (step 1) Or do I put the current address in the address field?

Problem  description:

I have a bitcoin wallet with some "money" it it that was created in multibit classic.


1. I exported the private key from multibit classic to an unencrypted text file
2. I created a wallet in electrum using address from my multibit classic wallet (shows the right wallet in read only mode - which is expected)
3. When I try do sweep in electrum though.. private key doesm't work (sweep button stays grayed out)

I'm not sure if this is the problem  but I read somewhere that multibit classic uses a compressed private key and electrum uncompressed.

I'm not fixated on using Electrum as my new wallet but multiclassic is obsolete so I need to migrate to another wallet (popular one so I don't run into this issue again) so I can make a transaction. Thanks for any help


Update:
Video on how to get the sweep button to become available. I had incorrectly selected the key with the date part which was appended at to end after a space.

However I still don't want to proceed with sweep because I read on this thread the following statement (I have a multibit classic key that starts with K).

"Multibit creates addresses using compressed private key, while Electrum uses uncompressed private keys. You can't decompress key - it will change public address, not allowing you to use your coins. Check first letter of your exported private key from Electrum. If first letter is K or L, it's compressed. If it's 5, you have uncompressed private key."

Has this issue been addressed? Is it safe for me to do the sweep? (don't want to lose my "money") Or do I have to do it another way?
