Has anyone stayed in an organisation after promotion to see their successor trash everything they ever did?

Because that's what's happening to me and it feels bloody awful. I am more senior but they have my old role, which I don't line manage, and have immediately set about changing pretty much everything. They're new to the company but no evaluation period, nothing, just blowing everything up. I have to be supportive and it really hurts. The majority of the team are furious. Any advice would be great as at the moment it just feels like a 'careful what you wish for' scenario.

Drop the rope. It’s not your problem anymore.

Yes. It's a shitshow. Complete incompetence.
I'm internally raging. Will probably leave in Jan as can't stand it.

Yes, and you really do just have to tell yourself “whelp it’s their role now”. I’ve left several positions and watched the transitions. Here’s are the things that I’ve found.

1. New eyes and energy can be good. Things change and sometimes if you stay too long you end up with the “That’s how we’ve always done it” syndrome. sometimes I haven’t recognized something that was out dated
2. Other people have had to watch me blow up their practices after they’ve moved on (see #1)
3. Different does not equal bad
4. Sometimes they learn the hard way why something is done a certain way
5. If someone ever asks you directly you can say “it wouldn’t have been my choice, but I’m sure they have a plan”
6. #1-4 don’t really matter anymore because I don’t own it anymore
7. I have moved on to a new role and am too busy to worry (see #2)
