Relicense old CC license versions (2.5 to 4.0

Hi guys
I have tried to update or relicense some of my projects here from creative commons 2.5 to 4.0 but haven't succeeded yet.
The thing is that with the CC 2.5 license there is a possible loophole which can get into trouble with copyright law in some cases if you release your work on another site.

Now I wanted to relicense my projects under CC 4.0 license but I don't want ot mess with unpublish and republish. I don't know if this messes up some statistics or some subscriber email distribution lists or in the worst case to rouse the grim database guarding dragon, burning villages and tracts of land making Smaug look like Grisu the little dragon

Changing the license will not have any effect on the ibles stats, comments, or anything else. you don't need to unpublish to change the license. There's a link near the edit button.

Oh I must have overlooked this...

This is handy. However this does not upgrade to 4.0. Why is that? Version 2.5 seems to be the only CC version here on instructables.com. Is there a reason that the whole system is not upgraded to 4.0?

That I can't help you with. You should suggest it in the feedback section.

There are upgrade guidelines linked here on the CC wiki. That page includes links to examples of mixed licensing, etc.

If you're looking for solid legal advice about licensing, look to the CC wiki disclaimer: Note and Disclaimer: Creative Commons is not a law firm. CC does not provide legal advice. Any information provided or linked to here is for general informational purposes only, and must not be relied upon as legal advice. You should consult your own lawyer if you need legal advice.

I.E.: obtain professional legal advice if you think it's important.

Personal opinion: usually these public licences are upwardly compatible with previous versions. They have to be; it's pretty difficult to call "backsies" on licencing--the work has already been released under a specific licence.
