Which version of EEPC are you using.
We have xml file in version 6.x but have sdb file in 5.x.
In EEM, machines tab, select the machine=>right click=>export configuratation and save the file.
you can't export an SDB file from EPO - you export an XML file, and use it in EETech (NOT WinTech).
v5 - Wintech, EEM and SDB
v6 - EETech, EPO and XML
