[How To] Sync Your iPhone / iPod With Your New Computer | Transfer iTunes Music And Applications Form One Computer To Another

by Rohit Khurana on October 12, 2009



When you buy a new computer or laptop PC, you may find trouble in transferring your iTunes Applications and Music from one computer to another. According to Apple iTunes software, one iPod / iPhone can sync with one computer at a time. If you try to sync with another computer, it will erase all the data present on the iPod / iPhone and Sync with the new device as if is a new iPod.

In this article I will share the methods to Sync it with new Computer without loosing your music and applications. I tested this method with my iPhone 3Gs when I changed my computer from my official Laptop (which I was initially using with iTunes) to my personal HP laptop.


Just to be safe, we must first take backup of all the music and application from the old computer. Follow the below steps to take your existing iTunes backup:

1. Open iTunes on old computer. Go to Edit > Preferences. Open the Advanced tab as seen below:



2. Check the option which says “Keep iTunes Media Folder Organized” and “Copy files to iTunes Media folder when adding to library” and click OK. Also note down the path highlighted in green above for later use.


3. Go to File > Library > Organize Library . Check the option to “Consolidate Files” and click OK.




4. It will take few minutes depending yon your music library file to consolidate all files into the iTunes Folder. After it is complete, open the path which is highlighted in second picture of this article in green color, copy the iTunes folder and back it up to some external drive or CD/DVD, wherever it fits. This is a backup for the case you loose some data. Although you might not need it if you follow rest of the steps smoothly.



5. Now Its time to De-authorize your old computer from your iTunes store. For the same, on your old computer, open iTunes, go to Store > Deauthorize Computer



6. Now you need to install iTunes latest version on your new computer. You can download iTunes Software from here. 


7. After installing the iTunes, you need to Authorize the New Computer by going to

Store > Authorize Computer . At this step, it will ask you your username and password for iTunes account. Enter the account which you used on your old computer.



8. Now its time to connect your iPod / iPhone to the new computer using the data cable. iTunes will detect your iPhone and will give you an option to Transfer your purchases to new computer. Select that option. It will synchronize your iPhone to your new computer. If there is no such option when you connect it, then right click on your phone in the iTunes sidebar and select the option to “Transfer Purchases”. This will copy your applications and music to the new computer.

hello! if my application is free, how to transfer it? same procedure on purchased application?

Laura October 28, 2010 at 2:21 am

Hi, thanks, at least my apps seem to be copying from my phone into the itunes library. I didn’t have any music on it to begin with and always managed that manually on my ipods so that it wouldn’t delete and replace what was on them, so hopefully whatever music i have on the dead computer (thus no back up of ANYTHING!) is an an ipod somewhere.
What I want to know, though, is if I get all my apps back in jive, and figure out a way to copy all my pictures onto the new computer (dying laptop) and then synch my phone with itunes, will i lose all my contact information since is has never been synched with this computer before? and what about my calendar info, and my to do list app with data in it?
thanks for your help!

Thanks for the article. I managed to transfer my iTunes store purchases to my new computer this way. I had some trouble copying music ripped from CDs though. It seems to me that the only way to do this is to use a third party iPod copy program, right? I tried the one called TouchCopy and it worked fine.

uhh… why dont you just plug your ipod into the new computer and do step 8? i just did that and it worked fine…

I tried transferring the Apps. Only the Podcasts and the Apps data got transferred. But not the Entire Music library.

Thank you so much! this was very helpful!!

What happened to me was, my computer got a bad virus so i had to reinstall windows, so everything was gone. So first i just re downloaded all my apps from the purchased option. Then when i wanted to sync though, it said that all my data would go away. Then after searching all over for the answer, my friend told me how to do it. Plug your ipod/ iphone into your new computer, on itunes, it should show up on the left. right click it, and click on back up. then when that is done, right click again on your ipod and press restore from back up. Then it will have all your data and be synced with your new computer!!!!!

Thank you so much!!! I hadn’t been able to find any other article that gave clear instructions on how to do this!! I was afraid that I would have to lose all of my apps.

Thanks again!!! 😀
