there wouldnt be a problem for me to just redeploy them on the other environment, it's just that i have my client's domains already connected to the service and i dont want to schedule a call with them just for them to change the dns again

We don't have the ability to move services in place between environments.

could i ask for a staff to do so?

It would be super cool if we could drag and drop railway.toml files into the canvas

i dont quite know where to find it

ive never interacted with one, and i just push updates to github and they just redeploy on the server

the services im trying to move are just a few static html files with a domain attached to them

so is that a no?

That is a no

You're welcome to manually recreate the service
