Upgrade Endless from Basic to Full

Hello everyone,

I`m new to the community, so my apologies if this topic has already been discussed.

I have installed Endless OS for my son on an old Lenovo Laptop, I`ve installed the basic image, he is happy and enjoys this OS, he only 6, does not speak English yet, however the OS is so child friendly and easy to use.

The question is:

Is there a way CLI or GUI where I can upgrade the image from Basic to Full, I have installed the full image on a VM to try it out and I can see there are a few differences, apps, etc.

I don`t have right now a large USB stick to download the big Image and I was just wondering if I can do it from an already installed basic OS installation.

Thank you.
