[imp] no db upgrade is needed if i upgrade vom db schema 4 to db schema 5 ?

[norbi]

hi list,

i have installed a horde5.04 and imp 6.04 and turba 4.0.3, then dumped a 
horde 4 database and finaly configred horde/imp to use this database.

after login in horde, -> Administration -> Configuration is see that the 
db schema dont need any update.

Is that true, or how can i dig this down?
