Hey, just wanted to say thank you @fbelavenuto. I upgraded / migrated my HP Microserver Gen8 from DSM 6.2 ds3615 / Jun 1.03b to ds3622xs+ DSM 7.1 / ARPL Beta-0.1 with no problems at all. The only manual intervention in the Loader configuration was to add a 2nd Mac address in the config file and change netif_num to "2". Booted up, migrated with DSM_DS3622xs+_42661.pat (with Update 1 included), and had to repair a couple of packages. Magic!
