Are you annoyed by syncing your existing iOS devices with a new computer? As all Apple devices owners might know, it isn't possible to sync your iPad, iPhone or iPod touch with more than one computer. When you connect your iPhone with a new computer, iTunes will always present the same pop-up window with the same message telling you to "erase and replace all iPhone content" on the device with the data in the new computer's iTunes library. Of course, you don't want to do that because all data will lose in that way. Making the new computer accept your iPhone can be difficult, but certainly not impossible. So let's go ahead and see how you can sync your iPhone, iPad or iPod Touch with a new computer without losing any existing content on the device. That is to say, we'll see how to make iTunes on the new computer accept your device as it is when syncing with a new computer.


Indeed, there are several ways to make it, but the easiest way is certainly to transfer all iPhone files and backups from the old computer to the new one. The necessary data is stored in several different locations, and we'll figure out what files to copy and where they go for both Mac OS X and Windows. This guide is aimed for iPhone users, but it also works with an iPad or iPod touch.

Syncing an iPhone with a New Mac by Copying Sync Data

1. Quit iTunes and disconnect your iPhone with neither an old computer nor a new one
2. Open the Home folder and copy the following directory from the old computer to the new one, located at "~/Music/iTunes".
Here "abc" is the username and the location is shown below.

3. Now open the user library directory and copy the backups from the old computer to the new one, located at "~/Library/Application Support/MobileSync/" shown below:

4. Copy over iTunes Preferences files as well:

5. Once all files are replaced on the new computer, connect the iPhone to the new Mac and launch iTunes, authorize the new computer and all data are stored in the iTunes of the new Mac.

Syncing an iPhone with a New Windows PC

1. For windows 7 users, the instructions are basically the same as above, but the files and folders you are looking to copy are stored in different locations. You'll need to copy the following directories and their contents from the old PC to the new PC:
C:\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync\
C:\Users\USERNAME\AppData\Roaming\Apple Computer\Preferences\
Here, the "USERNAME" is the user's account name, obviously.

2. For older versions of Windows users, iPhone backups are located at the following location instead:
C:\Documents and Settings\USER\Application Data\Apple Computer\MobileSync\Backup
Now launch iTunes and connect the iPhone, it should synchronize normally without any problem. Just authorize iTunes with your new PC and proceed, you'll be able to sync your iPhone with the new computer without worrying about the loss of data.
