There's no problem in using the legacy features in BuildMaster 6.1.28, though they are a bit hard to find. Our goal was that no new users would see them, but existing users could still access them.
You can directly navigate to the page where these are displayed with /schedules under an application, so for example http://buildmaster/applications/4/schedules. You should be able to also find this page on the Applications > MyApp4 > Settings > Legacy Build Triggers.
The Legacy Build Triggers link will only display when Legacy.ScmTriggers is checked (Admin > All Settings). This should be set if you have them (the legacy feature detector should have checked this, but it might not have).
These are also directly the database, happy to give more insight if you want to look across all apps. I don't believe there was a way to do this globally (but you can for 6.2 / non-legacy).
