Transfering Identity Safe data from old hard drive to new

Hello! 

I recently updated my computer and my old c: drive is now a second hard drive on my new system.  This also included moving from Windows xp 32 bit to W7 64 bit.  Is there a way to copy and paste my old identity safe file from the old c: drive to the new?  If so where is it founds and named?  I tried the Export / Import option, but could not figure it out.

Thanks!

Andy
