Here is how I did it. I am sure there are 1000 ways to skin this cat. Hopefully this helps somebody.
WAN devices on approx 20 different remote sites with links from 1MB to 100mb connection speed.
Requirements for my project
Update all windows 10 from x to Windows Version 1703 (OS Build 15063.729). We had multiple versions of Windows 10 ranging from 1511 to 1607.
Upload the 4GB install files to WAN locations only once.

Pay attention to difference in Version and Build.
Step 1 - Download ISO and copy to WAN Locations
Download the ISO for 1703 (or version you are trying to update to). You can use the Windows Media Creation Tool or if you want to download directly you can do this trick. Extract the contents of ISO to a folder of your choice.
Copy the entire contents of the folder above to each replication share. If you don't use replication shares this can be just a shared drive on a device in the same location as the device you want to upgrade. This is strickly for bandwidth reasons. If you are not concerned with bandwidth (and time to transfer 4gb) to each location then skip this step. Just make sure that whatever you setup your script in the “Windows Run As” has read Share and NTFS permissions.
Step 2 - Apply Labels to target Devices
Apply a Manual Label to each device you want to upgrade. I used Win10Upgrade-Nov1, Win10Upgrade-Nov7 etc so that you could easily go back and tell by the label when the upgrade was applied. Then after all was good and no issues removed all the manual labels.
Step 3 - Create the Script that does the work
Create Script that will do the actual upgrade. I will not give every script options here but here are the key ones.
Under Deploy Section select Microsoft Windows and choose your labels or devices to target. Again I used manual Labels created in Step 2 above.
Under Tasks Add a task and choose “Run a batch file…” with this as the bat file text. This is straight from this TechNet article. I used a bat file because I store the %kacelocalrepo% as a system variable that is set via GPO for other upgrades that are to large in size for Managed Installs.
%kacelocalrepo%\Win10Build15063\setup.exe /auto upgrade /installfrom %kacelocalrepo%\Win10Build15063\sources\install.wim /dynamicupdate disable
Step 4 - Run the Script
Either use the “Run Now” feature or schedule the script to run once at a specific time. Just personal preference here. There is probably some way to silently do this but I choose to allow the users to cancel because I would rather them cancel the install (its graceful) rather than power off the machine and corrupt the upgrade.
Step 5 - Go fishing! Most Important Step!
Go fishing in your favorite watering hole and come back to upgraded Windows 10 devices. Use KACE GO app to make your boss think you're doing this from land.
I did not use the Windows 10 media creation tool. I used the trick to download the ISO manually. The disadvantages (I think) of this are it installed 1703.0 during this process. Then after that I had to install Cumulative Update for November which is another 932 MB install. Granted at this point “Patch Management” does all my Cumulative Updates and the files are already on the replications shares, but you could have done this all in one task via Using the “Add updates to customized Windows images”. Is installing the Version upgrade separately than the Cumulative upgrade easier to troubleshoot? Sure it is… just throwing that out there as this minimizes downtime for your end users by doing Upgrade instead of doing an Upgrade and then an Update.
