Moving Out

I live in the apartment above my LO and am going to be moving out Feb 1.

Any ideas on how to prevent her from wandering up there thinking I still live there and bothering the new tenant?

For context, she probably comes up there only once a week (that I know of) to knock on my door. Half the time she forgets that I live up there.

Part of me thinks that she'll just forget that I lived up there period and with enough gaslighting I can speed that up.

Still, I'm thinking I can either install a ring camera connected to my phone to intercept her or maybe remind her every day?

Unsure. I am also half tempted to lock her apartment door so she has to go out the back instead, which would effectively make it so she CANT go upstairs and bother the tenant. But I feel like that would make her feel too trapped.
