I have a client that is currently using a version of YAFFS from about  mid
2007.  They would like to upgrade to the latest version of YAFFS.
All of their equipment in the field typically gets its load updated every
year with about 10 to 100 Meg of database stored in the filesystem.   I
have tested upgrading the file system from the old Yaffs to the latest
YAFFS and have not seen any problems.
Are there any pitfalls to upgrading the filesystem in the field (with
existing contents) that I should be aware of?
I have already verified that downgrades will not work.
