This is great information and thank you guys for the guide. It truly helped me migrate from an M10 with a shattered screen (but the touchscreen still works) to a new one with bigger storage. But I'd like to make my own recommendation on top of this. @thepeter recommends to exclude 'data/user-data/phablet/.cache'. This makes sense in general (most app cache directories are pretty disposable and will be rebuilt automatically and as necessary on your new device), but I would take an extra (as in, separate from the main archives you compress) .tgz archive of .cache/libertine-container/ (if you have one or even more than one container) as this will copy over all Libertine apps, app icons, dependencies, the container's rootfs etc. It's arguably just as important as user-data.tgz as that one copies the main Ubuntu Touch apps.
Are there any other directories within .cache which people think would be worthy of backing up and migrating, for genuinely useful and essential stuff like the Libertine apps, and so which should be made an exception to the exclusion command criteria?
