Firstly, you should to download and install the SafeWallet v2.x (desktop version) from here. This app will works in trial mode 14 days. This is enough. On the developers site you will see the newest version of the SafeWallet, try it if you like, but for import the latest version is not suitable in our case.
In second step, import you data into the SafeWallet. Then, do export all data into xml and that file the Safe+ can import (android version, not a desktop).
