Hi.

Is there a way to generate a xpub... Master public key from an old style Master public key in hex format (wallet file from 2014)?

I don't believe it is possible because the algorithm for the old style MPKs was totally different. What you can do is send all your bitcoins to a new format wallet and use the MPK of that. You can create a new wallet using file menu > new/restore and open wallet files using file > open.

The advantages of a new format wallet are:

- compressed public keys which take up less space on the blockchain so you save on transaction fees
- bip32 standard
- checksum in the seed mnemonic prevents typos

If you can import it into an electrum wallet then this is possibleto do. Although yu may have to transfer the coins from the wallet file into the new electrum wallet file so it'll cost you transaction fees to do this and you won't be able to use the old private keys with the new public key.
