Steven...The adsm server ptfs are cumulative...so you only need to
apply the latest maintenance to the server base.  For Aix 4.x it
gets a little more confusing...the packaging is broken into several
more pieces so you have the following filesets for the adsm server

adsm.license      (licensing)
adsm.server.com   (server common code)
adsm.server.dev   (server device support)
adsm.server.util  (server utilites...ie, ezadsm)
adsm.server.nls   (national language support...there may also
                   be a couple other components of this)

Each of these may potentially have a '.bff' file for each PTF level...or it
might not.  For PTF 11 which just came out, there is only updates to
.com (U446685) and .dev (U446684).  This is all that's new for PTF11..
however, if you jumped several ptf levels (eg, you are going from
2.1.5.6 to 2.1.5.11)...there may be some other ptfs you need to apply
to be at the latest for everything.  For example...the most recent
service for the utilities (.util fileset) is ptf9...so there is a file
for .util from ptf9 (U445128) that is the latest for that fileset.

I believe we always keep the latest level of each given fileset out on
the ftp server...that's why you'll see files from different ptf levels.
Plus, of course...there are different files for the different adsm aix
server levels (2.1.0.x and 2.1.5.x

Hope this clarifies...greg tevis
