Redeployment of German Units over the course of "Case White"

[PreußensGlanz]

Hi
Can anyone tell me if any bigger units(divisions and bigger) were redeployed to the West while the Polish campaign(general in September 1939) was still rolling(general in September 1939)?

I know that after the campaign a major redeployment went underway but that was not before early October.

Also I know that the limited Saar Offensive triggered some redeployment in the area that France conquered but those seem to be normal shifts of units already on the Westfront.
