Internal phone storage "upgrade" option

[Guest dnw6]

In settings, under "SD card and phone storage", specifically under "Internal phone storage", there's an "Upgrade" option. When I press it I get a warning message about not removing the sim, SD card or battery, but...what does this do? What's getting upgraded? I'm scared to hit confirm...
