Syncing contacts from iphone to laptop where both devices have different lists

If you, "authorize" the new laptop, you can sync your Contacts without erasing the iPhone.

On the new laptop launch iTunes. From the menu bar top of your screen click Store > Authorize This Computer

Then follow the instructions here to sync iPhone contacts to computer > iOS: Syncing with iTunes

Not helpful at all. I've got 177 contacts in my phone and only 35 transfer. Kind of useless.

Make a backup of both contact lists before starting. On you phone download and use the free app My Contacts Backup. This will backup your iPhone contacts to a file as an attachment to an email. Send this email to yourself. If necessary, you can open it later on your phone and re-import your contacts again. On your computer, use Outlook's export function to export a backup of your Outlook Contacts.

Next, before connecting your iPhone, open iTunes on your computer and disable automatic syncing (iTunes Preferences>Devices>check "Prevent iPods, iPhones...from syncing automatically". Now connect your phone and go to the Music page and uncheck Sync Music if you don't want to sync your music, and select to sync contacts with Outlook on the Info page. Now sync your phone and you should get a Merge prompt, which you should accept. When you're done you should get identical merged contacts on both your phone and Outlook.

Step 1. On your iPhone, tap on Settings. On the "Settings" menu, select "iCloud". You will then be taken to the iCloud Settings.

Step 2. Enable the "Contacts" setting and should you be informed that you'll have to merge your contacts to iCloud, tap "Merge".

Step 3. Now on your computer, go to iCloud.com and login with your iCloud credentials.

Step 4. Once you're logged in, click on the Contacts icon to access your address book and all iCloud features for the contacts you've uploaded.

Step 5. In the address book, click on the cog icon at the lower-left portion, click "Select All", and "Export vCard" afterwards.
