    1. Upgrading to Windows 10 Mobile at the moment (for those reading in the future, check the date of this post!) can be done through the Windows Insider Program - just download the app, follow the steps, check for updates, then wait (for around 2-3hours) for everything to download and install.

    2. In my experience with my sister's L535, all app data were preserved from Windows Phone 8.1 to Windows 10 Mobile.

    3. Here's the tricky part: since you mentioned "update will not be successful", that could mean a lot of things. If the upgrade was not successful because something went wrong, or you interrupted the upgrade, or your phone lost battery power, or the phone slipped from your table because the charging cable was snagged by a foot such that the battery was removed from the phone upon hitting the floor - then most probably you won't even be able to boot your phone again. In that case, you may try using the Windows Device Recovery Tool since that would be your best chance of reviving your phone.

    It's easy with the Insider app and (if there are no hiccup's) your data and apps stay untouched. To go back to 8.1 you need to have the WDRT ( windows device recovery tool).
    Before you install W10 on your phone be sure that you have the WDRT installed and working on your PC. ( During the roll back from W10 to 8.1 the apps and data on your phone will be erased).
    But the warning in the Insider app is not for nothing. Things can go wrong.
    BUT because you have to ask how/what to do I would not advice you to update your phone to W10.
    But if you still want to do it be sure you have stable WiFi, your battery does not run flat during the update (keep it connected to the charger), have patience (it can take some time so do not start to "push" buttons during the update process) and be sure you understand the risk. (It NEARLY always works but you COULD loose your data/phone).

    Yes.. I have upgraded my sister's Lumia 535 to Windows 10 and nothing went wrong. That's what my advice in post #2 is based on.

    Now, I'm going to side with Harrie-S - if you're so weary about upgrading your device to Windows 10, then probably you should just wait for the official update to be released. Re-read Harrie's last sentence - there are risks. The chances of something wrong going on is very small at this point in time, but still there is a chance.

    To illustrate, the chance of getting killed by a meteorite is very very very small (smaller than the chance of breaking your phone from an update), but it just happened a few days ago in India. The same goes with updating your phone (or any device), or riding an airplane, or crossing the street.

    So far it is quite safe, only failed on me once and that was human error on my part.

    Just advice to leave it charging as it would take some time to finish updating
