Updating an XPe device with EWF

[BeeFarmer]

How do folks update Xpe devices in the field? Lets say I have 500 units
with EWF activated and I want to install a QFE on all of them?

Bob,

Before applying updates, you will have to disable EWF using EWFMGR or you
can create an application that implements the EWF API set. Device Update
Agent is mechanism to update the systems in the field. QFE updates cannot be
applied directly. QFEs are designed to update the XPe database, so you will
have to do some work to create an update script for DUA.

Unfortunately I am not a programmer in this arena. I understand EWFMGR to
the point of having to diable it to load anything then committing it back.
My
next question is that you say for example the latest QFE can't be just
installed
Applying a QFE to a Deployed Device

How much work is this for a trained XPe programmer to build one for somone?

Bob,

Do you mean DUA script or the EWF API?

DUA scripting was designed to be very simple create scripts, but very
powerfull in feature set. Once you learn how to create a couple of scripts
it is very easy. Implementing EWF API into an application is straight
foward, but if all your doing is appying an update, call EWFMGR from a
script would be the best way to start.
