need a old DDOS image (5.1.x or 5.2.x)

Hi

I inherited 1x old DD630 running currently 5.0.1.0 which is obviously not under support anymore.

I am looking to do some testing/playing with it (I have many ideas; the most crusty one for me is to try to penetrate it as a hacker would do) and i would like to upgrade it to a higher version (I have images for 5.4.x, 5.7.x and 6.x) but due to the limitation of 2-generation jump, i cant use them; i thus need to hop to 5.1.x or 5.2.x.

Does anyone have a RPM of one of those versions to share? I cant seem to be able to download it from download center (links are dead).

Alternatively, if anyone has a way to trick the machine (eg, allow more than 2x generation upgrade, or force the update anyway), that would be ideal. There is no data on the machine anyway so im not even scared of any potential data-loss issues

thanks a lot for your help
