There is a reason for it.
The idea is that the people that has to do the migration have not enough
knowledge, and i would migrate first the servers that don't rely on a
extern  authentication.

1- database has normal it own authentication. And should be quite easy
to setup.
2- webserver the same, and it would have no authentication, and a
webserver could rely on a dabaseserver.
3-7 The authentication service  - LDAP 
 Groupware, file, print, proxy  servers will need some kind of
authentication for file access ore other.
8- this could perhaps be installed before the logon service, but now the
knowledge is larger.
9 this is the last server and as above for the knowledge.
10-11 no change.
