Do Not Attempt to Cancel an Operating System Transfer
After the transfer starts, the receiving unit's existing OS is effectively
deleted. If you interrupt the transfer before it is complete, the receiving
unit will not operate properly. You will then need to reinstall the OS
upgrade.
If You are Upgrading the Operating System on Multiple
Units
To perform an OS upgrade on multiple units, download and install the
OS into one unit and then transfer the OS upgrade from one unit to
another. This method is faster than installing it on each unit via a
computer. OS upgrades are released free of charge and you do not need
to obtain a certificate before you download or install them.
