Switching to a custom ROM, or switching between two custom ROMs, is definitely something that’s not for the faint of heart. Things can go wrong in the process, or you might skip a step or two, causing you to lose all of your important data in the process. Luckily, there are apps that aim to help you through this process, like Titanium Backup, but they’re not completely straightforward. If you want something that completely guides you through the process, then Migrate is the app for you.

Just like other backup apps, Migrate backs up your app data, APK files, permissions, call logs, messages, and more, but the app also goes to great lengths to ensure a friendly experience throughout the whole switching process.

Ein echtes "must have" für ein Android-Telephon, denn das zuverlässige Sichern ist wirklich manchmal notwendig. Die free version ist schon gut, doch die fünf Euro für die Pro sind gut investiert, weil man so mehrere Versionen der Backups anfertigen kann und einiges mehr.

Wer keinen Play Store nutzen möchte, gibts hier den alternativen Downloadlink:
