I'm going to start with my new iMac fresh ... plan to use an external drive cloned with SD as the source and drag files over that I want to keep.

question: should I boot from the new iMac or the cloned external drive when I start this process?
 
I do it from the boot drive. That way while the files are transferring you can be setting up software and accounts and configuring settings and everything else.

I am planning to start up from the new computer ... seems that you should be able to move files to the new computer regardless of what drive you booted from but I wasn't sure. thanks.
 
Something VERY IMPORTANT to be aware of...

You are going to "start fresh" and create a BRAND NEW account on the NEW iMac... is this correct?

If so, be aware that you could encounter "permissions problems" if you just drag stuff over from your cloned backup. The new iMac won't recognize your old account "as yours", even though it may have the same name and password. If you try to open some files, you may get an alert that you don't have permission to do so.

THERE'S AN EASY WORKAROUND FOR THIS.

Do this:
1. When you connect the SD cloned backup for the very first time, let its icon mount on the desktop but don't open it yet.
2. Click ONE TIME on the icon to select it
3. Type "command-i" (eye) to bring up the get info box
4. At the bottom of get info, click the lock and enter your password (the password for your NEW iMac)
5. In "sharing and permissions" put a check into "ignore ownership on this volume"
6. Close get info.

You can now copy from the backup (i.e., "from the old Mac") to the new iMac, and anything you copy will "come under the ownership" of your NEW account.

Something else to be aware of:
When it comes to copying stuff from your old home folder to the new one...
BE AWARE that you CANNOT COPY the "first level of subfolders" (the folders name documents, movies, music, pictures, etc.).
However ... you CAN COPY things that are INSIDE OF these folders, such as your iTunes music folder, the pictures folder, loose items, etc.

It's a little more work doing all this "manually", but not particularly difficult.
A good idea would be to keep a pencil and paper and write down what you've migrated, to keep track of things.

Thanks for the tips! This is the first time I've started fresh .... years of bloat from using migration assistant I suspect.
My delivery date was just updated .... now it's tomorrow rather than Monday so I'm sure I'll have a busy weekend.

I'm still a little confused about how to copy Mail and Quicken 2017 data but I'll search more and try to figure it out.

Thanks again!
 
Why not use Migration Assistant to do the file transfers ?

my goal is a fresh system and I have no idea what other 'stuff' migration assistant might bring along. also I consider this spring cleaning and I'm picking the files to bring along and which ones to leave behind.
 
Doing a fully-manual migration isn't necessarily "difficult", but it is time-consuming and requires some planning.

The most difficult (and complicated) folder to "migrate" is the user "Library" folder.
Many internal folders (most of which contain info for specific apps) to move -- or NOT move.

Pencil and paper ARE needed to keep notes!
 
It did take some time but overall it wasn't difficult. I was able to download all of my apps and luckily had the purchase information so it was easy to register them. Other than library files for my weather machine, I haven't found many that need to be migrated. FWIW, airdrop has been a life saver.
