You'll also note that the migration mentions it's supported from
the latest version of Tiger, which presumably will not be OS X
10.4.10.
Yes, it's pretty much a given that there will be a 10.4.11. Though
it was my impression that 11 wouldn't make any fundamental Server
changes that would affect the migration guide. But then again,
Apple is never entirely explicit about what they change in an
update even after they release it, so I suppose that could indeed
be the hold-up.
Well if you think back, at least as I recall (and I do have a very
foggy memory), the last point release of Panther made several changes
to Directory Services, specifically LDAP in terms of structure that
were required for migration. As these changes would be in motion at
the moment, should we presume that there will be a OS X 10.4.11
(hint: those who know can't say for certain but can at least
extrapolate from past OS releases) for similar reasons, and since
those changes might not be committed in code (say b/c OS X 10.4.11 is
still only a candidate release) and also given that docs tend to get
written later rather than sooner in the scheme of releases, well...
