Spark update 1.12 to 1.5 directly possible

[maddyman]

Hello all together,
is it possible to run the updater directly from the old version 1.12 up to 1.5?
I just tried to do this with my stand alone hardware device but after rebooting it still shows version 1.12 in the display.
Has anyone a solution for me?
thanks a lot
