CYOA-
I've never done a clean install, always just updated previous osx's. So I don't have the original files to do it.
So I'm thinking I'm going to have to download/create a bootable USB from Yosemite/el capitan or sierra. Then do a clean install from that, assuming that a clean install is a more manual version of migration.
The reason I want to do this is that there's a whole load of carryover from previous operating systems and files which aren't in use and which can't be deleted, so want to make sure those aren't carried over otherwise the whole thing is a waste of time...
Plus I need to make a back up of boot drive/documents as I've never had one, and after a couple of computer freak outs want to make sure if it does fall over totally I can bring all my shit back.

anyone done a migration from an internal drive to an external one?
I'm looking to do a clean install of el capitan or sierra onto an external drive, then migrate my current boot drive to it, as there's a load of leftover bits from me upgrading from 10.6.8 to current versions of the osx when I changed computers, and I'm hoping this clean up will improve performance.
Is this possible? Anyone done it? Since I'm not migrating from computer to computer, but rather computer to drive, think there may be complications that I'm not seeing...
