The biggest thing you need is the SID from the old samba. I think it _might_ 
have gone better if you had copied over all of the samba files and got 2.2.7 
running first, then upgrade it to 3.x. Microsoft networking/domains tie alot 
of stuff, to the network SID. Look on the old server for /var/lib/samba or 
/var/cache/samba folders. I 'think' what you are looking for is in the 
/var/cache/samba folder.

Something to try:
remove 3.x on new server
install 2.2.7 on new server
copy all files from /var/cache/samba from old server
test that machines login to 2.2.7 as before but with new server
down all workstations
upgrade 3.04 on top of 2.2.7
modify smb.conf file appropriately
   (ie.  valid users = @users  now is valid users = +users ) The @ is
          still supposed to work but I never could get it to.
Test login a workstation
