Hi,
From my point it is important to point out (and also discuss) that the
installation of a AOO 4.0 - our planned next major release - will not
migrate/use a user profile from a former installed AOO (or OOo) version.
This has been also mentioned in our blog "Your top questions answered", answer
to question 10 [1].
It is a consequence of the new version number - "4.0" - as the major version
number - "4" - is part of the folder/directory path to the user profile.
But, it is already a consequence of the completed renaming from "OpenOffice.org"
to "Apache OpenOffice" as the productname (in a certain form) is also part of
the folder/directory path to the user profile - see issue 121388.
We have a lot of trouble with the migration/usage of user profiles of former
installed OOo 3.x versions - unfortunately I could never reproduce these
problems and thus I could not work on a fix. Thus, not migrate/use a user
profile from former installed AOO (or OOo) versions would solve these problems.
Let the discussion begin :-)
