I don't move tyres around. I usually leave the front tyres to wear down then replace the front only. The rear tyres will soon wear out at around the same time as the 2nd set of front tyres so all four tyres can be replaced eventually.
So it goes in order like this when replacing new tyres - 2,4,2,4. You get the idea
The reason is that the rear tyres won't be doing as good job as brand new front tyres.
