I'm thinking about updating my NW60SP5 servers to eDir 8.7.3; they are
now running 8.6.2. From the installation instructions I gather that:

1. With 8.6.2 already installed, it is not necessary to update the schema.

2. I may need to force the backlink process to run, but it is unclear
whether this is done before or after the eDir update.

3. I may need to update NICI before running the eDir update.

If I'm reading this incorrectly, or if I should be aware of other
potential pitfalls, please post.
