Hi Rex,
It is possible to backport - but you will end up having to maintain the backport until you upgrade to 2.4 (ie - watch for patches to the 2.4 branch and keep cherry-picking). It would also be hard to only get the group assignment feature - it would be far easier (less conflicts) to take all the features from 2.4 and backport them to 2.3.
There are some API changes to plagiarism that would need testing and possibly portfolios (there may be more - that is just from memory).
Regards, Damyon
