Lifestyle upgrade

[billy17151]

Hi guys ..

Newbie on the block, and before you flame me, apparently I have to ask a question here, as I have not yet purchased.
I'm presently running blogs with the classic lifestyle theme, one of the early versions, attched to WP3.1, and seemed to go ok, until it was hacked.
OK, no surprises there, I hear you say .... so what I want to do is upgrade to the new Genesis/ Lifestyle/child setup, but wondered whether the change would be seemless.
What I mean is, can I just purchase the package, install the software and expect it to pick up my sql database, and then just tweek the theme settings for appearance?

Or am I missing something?

Sorry if it's been asked before, but have to ask, before I part with more money .... thx all.
