Upgraded bare metal install, using Jun's 1.02b boot loader, running DSM 6.1.2.15132 to 6.1.3.15152 via control panel.  Seems to have installed somewhat successfully, but it wouldn't come up via the GUI, seems fixed IP changed.  Found it on the Synology Assistant, with new IP and showing MIGRATABLE status. Clicked to "MIGRATE" retaining data/settings, took just about 2min and it was backup again, just on the new IP, reset it via the GUI, back to the fixed IP it had originally.
