I need to replace my HDD to SDD, and I think of upgrading to OS X Lion. Can I use my old backup in time machine HDD from Snow Leopard when I have clean install with Mac OS X Lion? I mean, can I open time machine in newly installed Mac OS X Lion to copy all the necessary files backup in Snow Leopard?
The Lion Migration Assistant has had no problems for me to restore users and applications from recent Snow Leopard external disks. I was pulling from Time Machine, but it shouldn't matter if it's just a bootable drive or has many point-in-time versions typical of Time Machine.
