If you have --try-test-paths in your preset, you might see: *"error: unrecognized arguments: --try-test-paths"*
There isn't a risk of data loss here, but it will either leave these presets unmigrated or else prevent you from using |mach try|. This is tracked in bug 1531364 <https://bugzilla.mozilla.org/show_bug.cgi?id=1531364>. However the solution is tricky and I suspect not many people will run into this. So if you see this please ping me or comment in the bug and I'll help sort you out.
