I recently did a clean install of Lion on my MacBook Pro and I've chosen to not use Migration Assistant because I don't want to move over a bunch of cruft under my 4+ year old home directory (Tiger > Leopard > SL). I've been very selective about the things I've moved over and all has gone well until I want to sync my iPhone. I've transferred purchases from the iPhone but if I check Sync Apps, iTunes wants to wipe and re-install everything! This wouldn't be a problem, except the time it would take to re-organize all my apps on the iPhone again. (Side note: Please Apple, give us an "auto-organize" button for apps!)
Any idea how to move over my old sync data files to avoid having to nuke/reinstall my iPhone's apps? Or is there another option to preserve how my apps are organizated?
Many thanks in advance,
OK, I wanted to close the loop on this. What I did was use Skyler's suggestion (backup/transfer purchaes/restore) but that alone didn't fully get my iPhone sync'ed with this new library. What I had to do was check-off the Sync Apps checkbox and click Sync. I then got a dialog window saying "The iPhone is synced with another iTunes library. Do you want to erase this iPhone and sync with this iTunes library?" The options were "Cancel" and "Erase and Sync." I chose "Cancel" (because I wanted to Google this more) but it appeared as though iTunes was still trying to sync! I quickly tried to cancel the sync by clicking the X in the status window but that didn't seem to have an immediate effect so I pulled the USB cable from my MacBook. At this point I was concerned that I really hosed up my iPhone/iTunes library but when I went back into the Apps tab and, lo and behold, the Sync Apps checkbox was checked and everything looked great! So I did another sync and it processed without any issues!
Everything seems fine now even with that slight hicup which is probably some sort of bug.
Many thanks to Skyler and everyone else who helped!
