8th gen ipads have only 32GB of storage, 11GB are used for OS and 3GB for system data, so, if you want to upgrade from iPadOS 18 to 26 the update requires 20GB of storage available in order to update making it almost impossible to update. The only options I see is to “restore” iPad with mac device or configurator, but just imagine doing this for hundreds of iPads, so the other option is to NOT update.

If you have\had this same issue let me know if you have found better options for this update and did you, your business or school district decided to stay in iPadOS 18 or not.

We ran into the same issue. What we did was Return to Service in mass and push out a software update to a smart group containing all 8th Gen iPads. 

The RTS deletes all content and automatically rejoins the network.

We struggle with the same.  RTS or I just update with Apple Configurator if I physically have the iPad.  It’s a pain for sure.

RTS did NOT work for us, but we figured out a solution that is about 90% successfull in our environment. We changed our “PreStage Enrollment” to require the latest OS before enrollment is processed. iPads go through normal enrollment process after the iPad has been updated, just needs a few clicks to get the device on the network. The other 10% is set aside since it needs hands on and time to be updated, but can be managed once we process the hundreds of iPads we need to update (hopefully last year of service for these 32GB bad boys)

Dear Community and Crashover,

 

We ran into the the problem with around ~700-800 devices.

Can you give a quick rundown what is meant by “Pre-Stage Enrollment” ?
I would be so glad if you can explain what u exactly did on a example with 1 IPAD.

​@KalleGer, PreStage Enrollment essentially loads preconfigured policies, attachments, apps, etc after it verifies with ASM that the device belongs to the school district\business. Jamf documentation here.

We made changes to the prestage enrolment and turned on “Minimum required iOS version” then selected the iOS version we wanted iPads to have before anything was loaded to them. This will require internet connection and an AP without security protection to speed Wi-Fi join process. (RTS keeps Wi-Fi information so it wont have to be entered again - thats why some comments before use this RTS process)

All this does is minimise the storage being used to allow for the update to go through. Keep in mind that some iPads still refused to update and gave the same storage problem message after being wiped.
