I noticed back during the XM8 competition that the Army never has a new weapon system unless there is a new cartridge.  The one exception was the M1 Garand.   

What the NGSW is doing is providing the bullet in 6.8m of 140 gn.  Each of the three "teams" is expected to provide a new cartridge, infantry rifle and squad automatic weapon.  Thus we have three competing systems.  One of those systems, or parts of all three systems, will be the next cartridge, rifle and SAW.  This will happen in 2022.

The question is what to do with the millions of M4s in the system.  If we replace the upper receiver with a gas piston design (rather then direct impingement) then no need for a buffer tube and thus we could have a folding stock.  What cartridge then works best?  300 BLK (7.62x35), 6.8 SPC or something else that would work in a short barreled PDW (9 to 11").  This would replace the 9mm pistol.

Keep them in 5.56mm and use them until they wear out and are replaced?

Use the new rifles on the front line and either expand that until it’s general issue or maintain the old rifles as second line equipment?

much of the support troops do not need an infantry rifle.  However a pistol is too under powered.  Thus a folding stock PDW with short barrel that could hit out to 300 m would be a better option.

Indeed, but you have a large amount of M4s which are probably issued anyway.

a large percentage need to have their upper receivers replaced.  Barrel wear and such.

If you need to refurbish things rather than use those made available by the NGSW I would have thought it would be cheaper to use existing supply lines to replace what you have rather than go to the bother of qualifying a new system, ammunition, armourers etc.

The Army is keeping the M4 in service for rear echelon roles.

The Army has just adopted brand new 9mm handguns and a brand new 9mm Subcompact Weapon (SCW). They are not going to do some foolish thing like spend a ton of money to convert old shagged out rifles to replace the brand new guns they just bought. Silly.

One would assume you might designate such a rifle as a "Carbine". Perhaps a compromise barrel length, say between 14-15"?
