Yep, that's why I'm planning to upgrade to OpenSolaris.

The casesensitivity option is just like utf8only and normalization, it can only
be set at creation time. The result from attempting to change it on an existing
filesystem:
# zfs set casesensitivity=mixed pool0/data1
cannot set property for 'pool0/data1': 'casesensitivity' is readonly

Regardless of the casesensitivity property setting, the file system preserves
the case of the name specified to create a file. This property cannot be
changed after the file system is created.
Thanks for any suggestions to help get around having to migrate the data.
