I have 2 HP V1910 switches running firmware version r1108p01 and 2 HP V1910 switches running r1111 and all 4 need to be running firmware version r1513p15. Can I take them from their old versions directly to r1513p15 or does anyone know if I have to step them through other versions first? Thank you for any help you can give me. Liz :)
