    Hi,

    what happens with my data if I upgrade to WP10 Preview? Some apps don't use onedrive to store theire appdata and if I reset my phone those data is lost.
    What happen to that data if I upgrade to WP10? Is the appdata migrated or lost?

    Btw. do you recommed an upgrade to WP10 10136?
    I had some problems with multiple mail accounts and mail live tile in the last preview and went back to WP8 because of this.

    best regards,
    Philipp

    Do a backup before updating. Of course that doesn't mean all data will be saved. The data that can't be saved will be lost

    What's important you?
    Messages, contacts, calls, most of settings + personalization and apps list will be restored.
    Most Games doesn't support back up feature, so don't expect to continue :-\

    It's good to see where Windows mobile future is!

    if you use multiple hard disks - be careful - I've seen it reset/change permissions on these and when I moved back, lost access to data - you need to go through some command line tricks to get it back.

    you'd think if you just swapped the boot drives you would be ok .. that's NOT the case ..
