I flew my quad with old firmware for a long time and no issues. I have also kept files of every update incase I need to go backwards. It may not be possible now to use it but of something bad happened with an update I could get into it to downgrade.
Just an FYI you cannot go backwards on the Inspire. The firmware verification process will not allow it.
