    So I'm planning on upgrading to Lion soon. What are the ramifications for my Time Machine disk? Will I need to reformat that disk before using it as a Time Machine for Lion? Just seems a little weird to have a series of differential backups on there with multiple OS's involved.

    Nope, just keep using it. It will keep track of the different updates without issue. If it didn't, it wouldn't be much of a backup system.

    You don't need to do anything. Just keep on using Time Machine like you always have.

    If you want to, you can do what I did. I waited a week with Lion, then deleted the TM backup and started with a fresh one just to reduce the size of the backup, but you don't need to do this otherwise.

    The only issue I can think of is if you had your backup drive in a different format than HFS+. but that would require quite a bit of hacking to accomplish.
