Wiki managers can only be replaced when they cannot perform their duties anymore, but your question is very broad in terms

Ok

Also, I asked that question because of this: unknown.png (1920×1080) (discordapp.com)

In that occasion, FANDOM reshuffled WM's to give them a brevity, working on a single wiki for a long time can bore anyone

Actually, there is a bigger reshuffle - we're assigned a new one too.

Also, they can retire for personal reasons.

And who will be the new wiki manager for Dinosaur Simulator?

They'll probably contact you next week?

Ok

Alright so I have got a new wiki manager named pcj, also he told me that the wiki representatives are having a re-organization which will have a blog soon
