I am currently in the process of migrating my 2003 domain to 2008 and ran into a potential problem. I have ran adprep32 /forestprep and that ran successfully but when I went to run adprep32 /domainprep it told me my domain needed to be running in native mode in order to do this. I raised the domain funcational level to native and re-ran adprep32 /domainprep and it completed successfully but want to make sure I didn't mess things up by running forestprep while the domain was in mixed mode then running domainprep when the domain was then in native mode.
Also, This network does file redirection and would like to know how to properly move this function to the new windows 2008 domain but I can post this as a seperate case my main concern is the question above.
Thanks in advance for all your help.
