Yes. You can still import keys and addresses you backed up with the previous version of Mycelium Wallet. Although we still offer users the option to create backups of single keys as well as create new single address accounts, we advise you to move your funds to a new HD account and backup your HD wallet master seed.
You can determine what kind of Account you have when in the Accounts tab, our HD Accounts will have an icon displaying several keys, a Single Address will display a single key next to it and a Watch-Only Account, an Account to which your device does not have the corresponding private key to spend the funds associated with that address.
As long as you keep your old backups, though, you will be able to recover your legacy accounts using Mycelium. To import a private key, switch to the «Accounts» tab, tap the icon with a key and plus symbol in the upper right corner, and select «Advanced». Then scan your encrypted private key and enter the password.
Please see the picture below for an example of such an legacy backup:
- Notice that it will list everything that is included within this backup at the top, everything included in this backup is encrypted using a random password with an checksum at the end, which is only displayed on your device, you will need to write it on your print out manually.
All the addresses can be found starting on the next page of the PDF, to import an address, you will have to scan the encrypted private key and enter the password. If you add more than one address from the same backup, you will only have to enter the password once.
Mycelium tries to keep the user as independent from us as possible, in case we might disappear, please see our BackUpUtil here on GitHub.
