Will ranking issues in Portfolio Planner impact other Kanban boards?

[Bea Tea]

I am learning to setup an advanced roadmap/portfolio using this Jira service with the URL /secure/PortfolioPlanView.jspa?id=

We have "ABC Initiatives" tickets ranked on a board by organization priority.

Each initiative is implemented by various teams Epic Group 1, Epic Group 2, etc.

I want to setup the roadmap and move things around under the Epic Group 1 engineering project.

1. Will moving things linke ranking/drag/drop in the Epic Group 1 impact the ABC Initiative ranking in any way? 

2. Some of the dependencies to other Projects are not displayed in the dependency tab. How do I enable visibility for all dependency against tickets in this project?
