During my PhD at a research institution I developed some software that I made public under the LGPL license (upon advice from the law people at this institution). I then moved to another research institution. The first institution have continued to support the software for the past 3 years, but they are going to run out of funding for it soon and will probably stop the support.
If this happens, I would like to take the software back and continue its development in the context of the work I do at my current research institution. The first problem is, I don't want the software to be under LGPL (my current institution uses other licenses that are less constraining, like MIT or BSD). Second, I don't want the original institution to be able to come and claim anything (like copyright, or money), should the software get a wider audience and/or be used commercially.
What should I ask the original institution? To simply re-license the software under a license that is appropriate for me? Something else?
