Hardwood over existing hardwood

Is it advisable to install solid hardwood over an existing hardwood floor? We were planning on gluing down engineered floor (opposite direction) over the floor, but like some of the solid floors better. If it is ok to install solid hardwood does it have to be nailed (would buy max 1/2" thick).
I have searched the flooring forums and haven't been able to find an answer. Any advice or experience you can provide would be appreciated!

Simple answer; don't install over old floor, for more reasons than I have time to tell you. TAKE UP THE OLD FLOOR!

We installed hardwood over existing hardwood going in the same direction - although there was no subfloor, so pulling it up wasnt really an option. No problems at all.

You had no subfloor? The hardwood was nailed every 16" directly to the joists? Did you do the work or did some contractor convince you that this was the situation? I Have not seen that in 40 years of remodeling old homes and will probably never see it. As I said before, TAKE UP THE OLD FLOOR!

Thank you both for your replies. Without going into too much detail, would you expect a problem with expansion or moisture or other issues?

TAKE UP THE OLD FLOOR! Expansion problem: probably. Moisture problem: most likely. Nailing problem: absolutely.
