Live rock or not?

[sonnyg]

I'm switching my salt water fish only tank that has been set up for 8 years to a reef tank.
Are the rocks in my tank live rocks?
I bought a couple of live rocks at the fish store.
Should I leave my old rocks in the tank?

How were you running your SW tank all this time? When did you buy the rocks and what kind are they? SH
