Syncing to new computer without losing data - Issue.

If the music is on your MBP and shows up in iTunes, and if your playlists show up in iTunes then your music will sync to the iPhone. Yes, it will be deleted, but it will then be restored.

If the music library on your new computer is the same as the music library on your old computer then when it erases the phone and syncs with the new computer the phone will end up with the same content it had before.

It is only iTunes content that will be deleted and replaced. If you do a backup first (actually, it's automatic when you do the update, but no harm in doing it twice) your messages will be restored from the backup. Use this sequence:

1. Connect the phone, right click on its name on the left in iTunes, and choose Backup.

2. Do the update.

3. If your messages do not reappear (they probably will) then right click on the iPhone again and choose "Restore from Backup", then select the backup that was done before the update.

4. Sync to restore your iTunes content if it didn't restore by itself.

If you don't have to upgrade just sync. It will only replace your iTunes content, not your app data.

As I've said several times, it does NOT mean that you will lose everything. I see no point in repeating myself again; do whatever you want.

This is the exact reason why I am switching to an android phone! **** itunes and **** apple for making it stupid. A lot of people have complained about this and are saying itunes is their main reason for switching as well.

If you bothered to read the thread you would see that the OP resolved the problem quite easily. So I must assume you are just here to troll. How much is Samsung paying you?

Firstly, my response was directed to the message with the picture. I don't have the same music as I had before, and unlike the OP who resolved it that way, I lost some music because in order to sync to my new computer I needed to erase all my music on my iphone first! I mean how stupid is that. Leave my music alone and put new music on it!

Look I love my iphone and I'm not hear to promote Samsung (fyi, there are other android companies). What I tried to say was that apple should stop being stupid and change itunes so that I can drag and drop, use multiple computers (because some households have that!), and not have a hassle with simple tasks like that! The ultimatium is change itunes or face costumers leaving your product behind! In the end I wish to keep using the iphone but solely because of itunes I can't and won't!

I'm agree 200%. I don't see why apple can "authorize" up to 5 computers with iTunes, but doesn't let you sync all 5 of them without erasing the data.

Joining this discussion very late. Anyway, a point to make is a point to make, no matter when.

I agree with Alex and Mr SwitchingPhones. It is very unreasonable of Apple to make such simple tasks a challenge. We common users love our data, music, ebooks, apps etc. And if Apple is obnoxious enough to choose to erase our data just because we want to add some more to it, then we choose not to use Apple. I bought one iPad and one MacAir. I love the hardware, but the software is such a pain. I am considering never to buy an Apple product again. What use is the hardware if there are so many compatibility issues.

I just wanted to add some ebooks I had for my daughter on my iPad from the same authorized computer, it doesn't let me do it...! I went to the Apple store and requested them to help. They couldn't do it too...! Can you believe it...! They say that Apple has upgraded and made some changes to make it more secure. Secure...! For god's sake, get some sense Apple. It high time. What, I need to do a PhD to learn how to transfer files...! Wake up. Make these simple tasks simple. Or loose us.
