If I release a piece of bioinformatics software under a certain license, e.g. LGPL, can I later decide to release parts or all of that software under a completely different license as part of another product, e.g. GPL? (leaving the original product and terms unaffected of course)
To distil the question to its most general form, is dual-licensing always possible, or can some licenses prevent the owner from re-releasing under different license(s)?
Thanks
On top of that, you can have a look at http://en.wikipedia.org/wiki/Multi-licensing and get some examples on 'License compatibility'.
Very clear answer, thanks.
