[Yaffs] yaffsVersion meaning

Hi,

If yaffsVersion is never set to 2 (ie. always set to 1), does that mean
that a partition that was written with ancient yaffs1 code on a 2.4
kernel will be able to be read/written using modern yaffs2 code and a 2.6.22
kernel with a 512/16 part?

Thanks for any help or info in advance.
