Re: How I can migrate my lumia 535 into windows 10
Hi, I'm assuming you want to upgrade from WP8.1 to Win10 mobile.
First download the 'Upgrade advisor' app from the store and run it.
This will show if you are eligible for the official update.
If the app shows you are, then enable the upgrade in the app and check for updates in settings > update phone.
If you have any further info or require more help, join the Windows Central forums so that you can reply to this thread.
