The only things you can truly convert over to 4e wholesale is the PI (Product Identity or "fluff"; which was not released as part of the OGL) and the non-mechanical OGC.
The mechanical OGC in any converted product remains forever OGC, all you are doing is expressing the OGC in 4e mechanical terms using 4e References and creating new 4e rules to fill the gaps.
This could be summarised: a GSL conversion of an OGL product will reproduce the fluff (which may or may not have been OGC) and will replace the old mechanics (which may or may not have been OGC, but probably were to a large extent) with new mechanics which are stated using References from the new SRD.

This "new expression" of the OGC is not OGC and essentially becomes 4e GSC (4e Game System Content).
Unless I missed it, the licence does not define any such concept. What we have is text the copyright of which belongs (principally if not entirely) to the publisher, but which incorporates 4e References licensed under the GSL.

You cannot take this content back with you if you attempt to return to the OGL. Nor can you return your PI once you convert
Well, there are two issues here.
Any attempt to reproduce the content of a publication licensed under the GSL as a publication licensed under the OGL would be a violation of the GSL. But the issue I was considering was whether it would also be a violation of clause 5 of the OGL. And that clause only requires one to have authority to contribute the OGC in the publication. So, provided that everything appearing in the OGL version that had also appeared in the GSL version was not OGC, clause 5 would not come into play.
(I should add - I am assuming here what seems to me to be an overly wide reading of Clause 5. I do not think that clause 5 requires me to not be under contractual obligation not to contribute the OGC in question. I think that it only requires me to have sufficient rights in the OGC in question that, in purporting to contribute it, I am not infringing anyone else's property rights. But perhaps I am reading clause 5 too narrowly.)

This means anything you convert over to 4e via the GSL, be it PI or OGC is considered "non-returnable" to the OGL for the Licensee. However, oddly enough the OGC is still OGC and so any one else, except for the Licensee can use it, which seems odd, but there you have it
That is because the OGL does not preclude use of that OGC. And the Licensee would also enjoy the benefit of that non-preclusion - that is, a backwards conversion is forbidden by the GSL but (provided the OGC declaration is done properly) does not appear to be forbidden by clause 5 of the OGL.

In addition, once your PI becomes "non-returnable" to the OGL it is that way forever. No returning to the OGL for that PI or anything that Wizards of the Coast could construe as that PI.
Again these prohibitions arise under the GSL. As far as the OGL is concerned, what seems to matter (given clause 5) is proper declaration of OGC.

I am a lawyer, but an academic one, who does not teach contract and who does not have a practice certificate. So none of the above is legal advice - just an attempt to work out the implications of each licence.
Nor am I encouraging anyone to backwards convert in violation of obligations under the GSL - I'm just trying to understand the legal implications of doing so.
