Migrate from EndNote X to X2

Hi,

During a training I was told that if we open an endnote library with endnote X2, then we won’t be able to open it with endnote X. I haven’t been able to reproduce this. Does anyone know if this true? or maybe it is true in some conditions, but in which conditions?

Thanks

I think X can open library files created by X2, but X doesn’t support >500 groups, so you won’t see them. In general, you can expect backward compatibility, but not forward. But between X, X1, X2, it seems you can open files at least.
