It's still exactly the same size, it's just that the store you copied 
over had incorrect usage information as revealed by the syslog message 
you saw.

This incorrect information will most likely have been caused by a 
client being disconnected without logging out first. Did you forcefully 
terminate either client or server during the move? Is there anything 
interesting in the client logs?
