It all sounds a bit odd but maybe I'm missing something.
How are you going to run scripts if you don't have access to any of the systems?
Is someone going to run them for you and if so, do you know what information you need? - This is correct. Someone is going to run it.
Are you the one who will be moving all of these or are you expected to come up with a plan to move them and deliver it to someone else? I feel bad for you already... - Yes at a later point of time
As for how everything runs today, you would need identify what information you need that would impact migrating. It's just seems too broad at this point - unknown versions, package storage and usage, how you plan to upgrade reports, hardware/OS changes, etc.
In terms of deployment settings, that seems like something you need to figure out based upon what and how you deploy based on business needs, versions. There are hundreds of questions you need to ask the business. Maybe sit down and come up with all the questions to ask the business and come up with a list of things you need to know about each component and work on your scripts from there.

I have tried to ask how much I could.but certainly need some help more
