Sequencer - can't export camera?

I have a bunch of shots with cameras inside my project. Now I want to migrate it to another project - how can I do it? When I migrating sequencer file, cameras are not attached to it. Are they stored inside the level? How can I move them to another project with another level?

Figured it by myself.
I can just copy/paste anything I need from world outliner to any level/project.

That won’t work across different computers obviously, do you happen to have some more insight into this since your solution?
