Time Machine backup replacing newer applications with older versions?

Hi guys,

I recently upgraded my internal hard drive and had to start with my original install disc for Leopard. I made my way back up to 10.8.2 Mountain Lion, but I don't have any of my files or programs on here. I have multiple Time Machine backups from before my hard drive upgrade (also 10.8.2).

I now have iLife '11 on my MBP, but all of my TM backups only have iLife '09 on it.

My question is, if I restore from backup will TM overwrite iLife '11 and revert it back to iLife '09? I would obviously like to keep iLife '11 instead of it reveritng back to '09.

Thank you all in advance!
