Managing Calendar

We'll start with a simple three-for-one special. Believe it or not, the core categories of calendar, contacts, and photos are among the easiest things to migrate from iOS to Android.

All you've gotta do is install the Google Drive app onto your iPhone, then sign into the app using your primary Google account. (If you don't yet have a Google account, the app will give you the opportunity to create one.)

On your iPhone, open the Drive app's menu, select "Settings" and then "Backup." If you're interested in moving over some but not all of the available areas, you can tap whichever area you want to handle individually. If you want to move them all at once, just tap the blue "Start Backup" button to let the app deal with everything together.

This process may take a while and burn through a fair amount of data, so you'll probably want to save it for a time when your phone can be plugged in, connected to a reliable Wi-Fi network, and not immediately needed for anything else. That being said, you can always hit pause and start things up again later, so don't worry too much about the timing.

All done? Excellent: Now just sign into your new Android phone with that same Google account. You should be able to find your calendar data in the Google Calendar app, your contacts data in the Google Contacts app, and all of your photos and videos in the Google Photos app. (Depending on your device, some or all of those apps may be preinstalled by default; if any of them is not, you can simply download and install it from the Google Play Store.)

One exception to the rule: If your contacts or calendar data is connected to a Microsoft Exchange account, it won't be moved over as part of this process. In that scenario, you'll need to add your Exchange account into the Gmail app on your Android phone (see the next section for more detail), and your contacts and calendar info should then automatically show up in the appropriate apps.
