 @b05df304 oh well. The one-image overview is very nice. 
 @2dfc6694 basically the arrows show consumption paths

For example LGPL v2.1 and LGPL v3+ are not compatible, neither license can include code from the other nor can you upgrade one to the other.

However both of these can be rolled into a GPLv3 license and therefore you can merge them under that license.
