Zebra Android OS Update Options


What is your preferred MobiControl driven OS / Firmware update method for Zebra Android devices, and why? I am trying to validate the best deployment strategy given the regular release of Lifeguard updates, sometimes in the 30-50MB range, and the occasional release of full size updates in the 200-300MB range. I am considering multiple aspects including, but not limited to, minimizing impact to the network and minimizing impact to the end users. Do you have users self-serve the update? Do you schedule them to all occur at the same time? Do you preload the update files and then execute the installation separately?


Delivery Mechanism Options

- File Sync Rule

- Package

- MX Profile that points to an FTP server or other download location.

- Other?


Application Mechanism Options

- install_system_update as a post install script in the package

- install_system_update as a standalone script applied on demand

- install_system_update in a script in a package that is applied via a Self-Serve package

- MX profile for applying the OS update applied as a package

- Zebra custom app for applying OS Updates. 

- Other?

Interesting questions.

We have tried different methods for patching Zebra devices. We are currently testing patch deployment using a profile with a post-install script that executes the OS update.

We have set up a "patch window" file sync to ensure that we only run OS updates during night.

The filesync rule downloads a file(if its newer) from our Soti server and we use custom data to fetch the information in the file and use it as profile filter,

At 11.45PM a Powershell script on the server changes the file to contain current weekday and Patch=Enabled.

At 5.30AM the script changes the file to current weekday and Patch=Disabled

File sync schedule is at 11:45PM and 5.30AM. 

We have been testing this for a while and are almost ready to run it in production.

I like the novelty of this approach, but I might be missing a part of it. Are you using the File Sync rule to distribute the update zip as well as the custom file that the Custom Data rule extracts from or is the update zip distributed as part of the Profile? At first I was wondering why you wouldn't just use the schedule window for Profile application but I guess that would only be a one time window whereas your Powershell script enables this window to reopen every single night. Neat.

We are only using file sync for the ini file. The patch is distributed as a part of a profile. And you are right, our script enables a fully automated deplyment schedule.
