Honestly the thing nobody warns you about with leaving Opsgenie is that the alerting is the easy part. it's the rota that gets you. Someone books a week off and suddenly you're hand-editing overrides at 11pm so nobody gets paged into their holiday.
For those who already moved off it: what are you actually using for the scheduling side? JSM's built-in thing, something external, or just manual overrides every time?
And did the per-seat pricing make you quietly trim who you keep on the rota? curious if that's a real effect or just me overthinking it.
Trying to work out if this is a common headache or only a couple of teams. Full disclosure, I'm tinkering with building something simpler for it, so I'm genuinely nosy about how people cope right now.
