A web adapter is a single object and can't be started twice. You could start it, stop it, and then start it again f that is what you are after. If you want multiple copies of an adapter running at the same time, you'll actually need multiple adapters. You might be able to organize a single adapter such that your controls are cloned and then operate on a single "adapter", but you'd really need to understand your automations and adapter very well and this would be something you'd either want to do on your own, or get some professional hands-on assistance with.

The easiest way would be to make a copy of your adapter and it's automations. You'd need to edit each of the os files and change the IDs of each of them. You could then re-import them into your solution. You'd also need to change the names of each unless you're importing them into a new project.

If you wish to do that, I would practice on a really simple project first, so you know exactly what to change.
