Currently I have all the "Consumer Edition" builds from 1507-2009, but I've just recently realized that the "Business Edition" builds have both Pro & Enterprise where the Consumer Editions don't have Enterprise at all. I never thought the Business Edition builds would come with Pro as well as Enterprise so I never bothered to download them. But I just happened to download a Business Edition build last night and saw that it includes Pro & Enterprise. So now I'm trying to download all the "Business Edition" builds, but for some reason it appears there are no ISO's in the MVS Repo for 1507-1803. Are there any other sources for those older versions?
downloads are probably taken down for out of support versions, but you can still create both business and consumer ISOs for 1507-21H1 via mediacreationtool.bat
yes, we never uploaded them because of the lack of support check @GezoeSloog's signature and you’ll find every business ISO.
