Noob Alert! All of the Time Machine backups tht I have were from 10.7.1. This week, I took my wife's iMac in for the Seagate 1TB drive replacement program. They said that the new HDD has 10.6.8 on it. My question is, can I restore files from my Time Machine backups to 10.6.8 or do I need to upgrade it to 10.7.1 first and then restore from the TM backups? Thanks.
