I recently migrated all data from an old desktop running Mavericks to a new desktop running Yosemite using a Time Machine backup and Migration Assistant. Since then, the iCloud keychain on my various devices (iPhone, iPad, laptop, new desktop) is filled with very old passwords. These old passwords are the passwords still stored in the login keychain of my old desktop, left over from before iCloud keychain existed. My guess that when these login keychain items were first loaded onto the new computer, they were considered newer than the corresponding iCloud keychain items and so the Mac decided that the iCloud keychain items needed to be updated. Of course, I could have a completely incorrect diagnosis.
The most pressing question:
1. How do I restore my iCloud keychain to its pre-migration state? I still have the old iCloud keychain on my old Mavericks desktop (which hasn't been connected to the internet since the migration started) and, presumably, in my Time Machine backups. Is there some way for me to reload these old values into the iCloud keychain in batch?
The less pressing question:
2. What did I do wrong? Presumably many people have keychains in the same state as mine: current passwords in the iCloud keychain and older passwords in the login keychain, but google searches haven't revealed anyone experiencing this same problem.
Thanks for any help.
