I'll throw in our experience if it helps anyone.

We just upgraded from 4.2.0 to 5.1.6.1 on W2K.  We were using subfile
backups at 4.2.0 and these were not expiring properly.  This was fixed at
5.1.5.x when I did a test migration to it.  When doing a test migration to
5.1.6.1 we found that there was a problem trying to recover any subfile
backups - client got an error (Error 8 getting backup row for object XXX).

The process we followed which seems to have worked was:
Upgrade to 4.2.3.3 - run expiration twice (cleans up sub file backups).
Upgrade to 5.1.0.0
Upgrade to 5.1.1.0
Upgrade to 5.1.6.2

Redo licences at 5.1.6.1.  Not sure if we needed to go to 5.1.0.0 and
5.1.1.0 before 5.1.6.1 (couldn't we just install 5.1.6.1 then install
licences from a 5.1.5 base version?) but this was according to the readmes.

Steven,

We just upgraded a few weeks ago (AIX 4.3.3) and we were told by support,
to go from 4.2.1 to 5.1.0 to 5.1.5.  Make sure you do not start the server
until you've completed installing 5.1.5.  You will have to reset your
license file(s) as well.
