All is same as on a DM900/920 or even a DM7020HD (Tools such as DreamBoxEdit, DreamSet, DCC, Putty, Telnet, FTP can be used). DreamUp is only for older boxes to flash the firmware. On the DreamOne/Two you flash it as on DM7020HD via the webinterface (IP of the box once set to Flashing mode).
The issue is mostly related to the image you installed, was it the same as on your DM7020HD ? Probably the best is to install the same image you were used to use on your DM7020HD, and then you will see that all will work smoothly then.
