"Newbie" seeking advice - complex question
I will be migrating from a PC to a MacBook with an SSD (my first Mac since the mid 80s). My PC music folder is > 50GB, most in the iTunes folder, and I want to move it to an external HDD. I do not want to use iTunes Match. I have an iPad, which has a subset of my music on it, and an old 32 GB iPod which is almost full with music. I have been syncing them to the PC and will migrate that to the MacBook at some point.
I have not run Migration Assistant yet. The MacBook only has an Admin account, so far. I think that I want to move the PC (Windows 8.1 - not upgraded to 10 yet) Music folder, and make sure that iTunes on the PC still works, before running Migration Assistant. I assume (hope) that Migration Assistant will properly migrate iTunes settings to the MacBook so that it will use the external HDD (formatted for the PC). When I want to use iTunes on the MacBook I will plug in the external HDD.
So I am seeking advice that what I want to do makes sense and will not have any adverse consequences. TIA
MacBook Air, OS X Yosemite (10.10.4), also old iPod Touch
