x86 and x64 projects compatibility on the same version of unity

Good day,

I would like to ask if it is possible the project I am working on on Unity 5.1.2f1 x64 to be continued on a Unity 5.1.2f1 x86? Will it work if I copy my whole project, that I am making with Unity x64 and import it in the x86 version?

Thanks in advance.
