Have just installed 10.6 on a separate partition...

Question

and want iTunes to use my existing music library from the (still existing) previous partition, so I can sync my iPhone without wiping it. I've "transferred purchases" so any music I bought off iTunes and all apps etc are on the new install, but none of my music I uploaded from CD etc is there. I tried changing the iTunes library location to the location of my iTunes library on my old installation (also 10.6 - it's complicated - don't ask, lol) but it doesn't auto update the music library on the new one with everything that's in the old one.
I have authorised the computer, and signed into the same iTunes account, but want to try and avoid the situation where I have two distinct iTunes libraries where if I update one, every time I sync my iPhone on the other, the iPhone gets wiped again. Or at least, if it does, then there's no difference between the music collections. Is it even possible to do it that way. Is Home Sharing a way round it?
Thanks in advance all you iTunes guru's out there...

Answer 1

I do not know if this is what you are looking for, but you can use you old library and maybe go forward from there.
You should try to make iTunes on your new partition 'use' the library on the old partition.
Close iTunes and start it up holding down the 'option' key. Choose 'select library' and try to locate your library on the old partition (it should be somewhere in ~users/Music/iTunes).
If the library is still on that partition and you did not move your media folder, this should work.
A possible issue can be that an error pops up saying that you are not autorized to access that file. Then reboot you Mac in the old partition and give you new partitions user account access to the library file.
