The question is related to this one:
I would agree with The comment of Tim to transpose up the a- minor scale (or the b-minor down).
Then I thought there would be a problem with open strings in the first „position“. But there are other frets to start with, e.g. the 5th.
I think it would be better to understand the tuning system of a guitar and the pattern of the minor scales in general.
Or am I missing something?
