     @brhfl Well yeah, I was wondering if I could just upgrade it to 4.0, and also whether it's compatible to AGPLv3+ for example.

     @screwtape hmm more details of your concerns? away from cc vs. up to 4.0?

     @screwtape I think (at least for most cases, and assuming there's still an equivalent 4.0 version*) you can just upgrade it. I don't see anything that would make it incompatible with AGPLv3+, but I'm not expert enough in the relevant areas to say that 100%.

     * For example, there's no 4.0 equivalent to the older Sampling+ license for music.

     @brhfl thanks. Basically I'm referencing something from 2008 that's under cc 2.0, so it's good to hear that it won't become-revoked, and sounds like I can either issue my own derivation under cc 4.0 or agplv3+ (since I'm not affecting the license of the original work).

     @screwtape i _think_ it would be similar with gpl licenses (apologies i know much less about agpl) but there are (or have been in the past) compatibility concerns that i'm ill-equipped to speak on, though looking for guides like https://wiki.creativecommons.org/wiki/ShareAlike_compatibility_analysis:_GPL might be a starting point.

     @screwtape essentially, as long as there's a single copy of each out in the wild, you have two otherwise identical products, each with separate licenses. cc sorta kinda outlines what goes into upgrading at https://wiki.creativecommons.org/wiki/4.0_upgrade_guidelines#Logistics_of_applying_4.0, but there isn't much to it because again you're just sort of... doing a new one.

     @screwtape gotcha! i'm not a lawyer so... y'know, grain of salt, but i can tell you my understanding. cc licenses are irrevocable. but, as the rights-holder, you are free to 'rerelease' such a work under a more- or less-permissive license. you can freely attempt to scrub all instances of the earlier version if you so desire. but the irrevocability means that if someone has a copy of the version that was marked cc 2.0 out there, _that is still binding_.
