I would like to recreate Judge Engine of Online Judge named HUSTOJ. However, HUSTOJ was released under the GPL-2.0 license.
I would like to release a new Judge Engine with AGPL-3.0.
I know that GPL-2.0 and AGPL-2.0 are incompatible licenses. However, I left the question because I do not know whether GPL-2.0 and AGPL-3.0 are compatible with each other, and whether I can set a license in this situation.
I would appreciate it if you know this.
