Hi,

I installed Lion GM (11A511), by pulling the DMG installer onto a USB drive, and clean installing from there. I then migrated my apps, data, user settings, from a TM backup, and it works perfectly.

Now, when the Final version comes out, would there be ANY reason to move onto the commercial version (if 11A511 turns out to be the Final)? And, if Apple does make some changes, would it not just be buying the newest version, and then clean installing from a DMG/USB drive solution, and then migrating from my TM?

As discussed in numerous threads, the Gold Master is the final release version, until some show stopping bug may occur, but as it seems, it hasn't happened yet, thus you as developer can use the GM as intended.
 
I know that.

What I really would like to know is if my "migration" method is solid, and I am not having any "leftover" from the SL installation when I migrate apps, and user settings from TM? The OS installation is fresh, but by not reinstalling everything, am I dragging with me a bunch of crap?

I'm pretty sure Apple will remove the "Leftover" once the upgrade is finish. So I think a clean installation is no needed.
 
If 11A511 turns out to be the final retail version then you are good to go. If it's a different version# then you might want to track down what change(s) occurred. If it's nothing major (or nothing that affects how you use your machine at least) then it may not be worth reinstalling again -- that's your call. 10.7.1 will be out soon enough though.
 
10.7.1 needs to come out fast after the release if the GM is final because there are still a lot of bugs.. example, I have to turn OFF inertia scrolling constantly because it keeps turning back on even though the setting says its off.

That and some other minor items I experience too. None of these should, IMHO, prevent the release to the public but a 10.7.1 soon after is warranted.

There is an item I reported with Safari in GM that Apple seems to be interested in...they keep coming back to me for more info on it but it too should not stop the release though it is an annoying item.

My initial Lion was on a fresh formatted drive, the latest update, GM release simply upgraded through the installation when used from a torrent files install/setup extracted from a zip. No need to revert back to SL to initiate the install.
 
There will be no leftovers from the Snow Leopard system. However, there will be leftovers from your Library and Application Data, if you choose to migrate your installed apps instead of reinstalling them on the fresh system.

These leftovers may include cache files. Although Time Machine isn't supposed to back that up, it might not be able to identify the cache files of every application except Apple's own apps and system caches.

When you delete an app from the Applications folder, you don't delete the preferences left in User/Library/Application Data. Those files will get migrated back when you use Migration Assistant to restore your installed apps, I think.

This is not a big problem, as those files won't ever get accessed by anything. They will just take up disk space, but you can always manually delete them or use a cleaner utility to do it for you.

Basically, there will be no leftovers from you old system, just from your old apps. But you had those anyway while on Snow Leopard, and they're easy and safe to track down and delete.

I'm not 100% sure about what I just said, but from my experience this is how OS X works. Thankfully there is no Registry or anything messy like that like on Windows, so there is no true need to do a clean install, unless your hard drive has 200 GB of random trash files, which is too much to simply track down and manually delete.
