Mainly around the 67/68 and DHCP, see below:
Sounds great, thanks for sharing! Guess I'll upgrade later today.
Ive just upgraded 6 single devices (including some 67s) and 3 HA pairs (84s and 100s) They didn't drop off the dashboard and are passing traffic so basic tests aok 😉
@cmr - Can see you've applied it as well due to the number of alerts received 😂
Let us know how it holds out as we need to take another customer to 15.x.
MX67 HA-pair sucessfully upgraded without any hickups.
