Upgrade from Debian 4 to 5

First of all, sorry about my weird english.
Guys i want to upgrade my server machine from Debian 4 to Debian 5 because of some bugs i have (f.e. screens, crashes sometimes). In the server, there is installed the DA panel, will work after upgrade or not?
Please answer me fast, thank you

well i have servers running debian 3, 4 and 5.
they all did work.
only 1 upgrade from 4 to 5 and i just rebuilded DA because i was also doing a new custombuild but it was working.

I upgraded from 4 to 5 and have had no problems with DA.
