MDM migration with backup restore using iMazing Configurator blueprint

Hi there! I'm currently planing the MDM migration (from Sophos to Intune) at my company. One central problem we stumbled across is the need to restore a backup when re-doing ADE enrolment. I know it's a common issue (with the workaround to use another device to restore the backup, create a new backup and restore this one on the original device.. not practical in an enterprise environment with 500+ devices.

So.. I came across the tool "iMazing Configurator" which claims it can do exactly what's needed for MDM migration without loss of user data.

Here's the guide I found: Bulk migrate iPhones or iPads registered in ABM or ASM to another MDM solution while keeping their data (with iMazing Configurator)

My question: Has anyone tested this software/feature? Is it stable enough to use? Or is there any better way to perform the migration from one MDM to another without losing user data?
