How update to latest Beta software of Mac OS X without having to update incrementally I'm right now on Beta 2 of Mac OS X 10.11 "El Capitan" (15A204h)

The Mac App Store wants me to update to Beta 3 

I know that the latest Beta is Beta 7 (15A263e)



Redeeming the code for Beta 7 doesn't work.

 

It seems that this is the same code that got me Beta 1  

Image from Purchases section of App Store:


And I cannot see in "Purchases" section of App Store Beta 7 available. 

Is there a way to upgrade from Beta 2 (or any earlier version) to Beta 7 directly. Without having to upgrade 5 times?
You can't - Apple hasn't released a combo updater (yet) and we're at β7 build 15A263e.

You can duplicate this radar if you find it a waste of time.


http://www.openradar.me/22307567 The title isn't strictly correct - all installers so far are incremental.


So, your best bet is to get decent connection to the network and softwareupdate --download --all and then softwareupdate --install --all (or just straight install which downloads then installs)
