Is there any disadvantage to upgrading Win10->Win11 as opposed to a fresh install?

@OP I have been mulling over the essentially same issue for some time and did a test with RevoUninstaller (that I normally do not use) recently. I cleared out several GBs of crud with some gentle cleaning (I do not want to use aggressive cleaning) and there may still be several GBs of crud left in the old W10 machine (which BTW still runs very well, both with a lot of crud or with less crud, I don't notice a difference) These several GBs of crud may be carried over in case of a cloning to a new W10 machine & upgrade to W11, but I can confirm that several GBs of crud is likely to be inconsequential from a practical point of view.

Looking at the issue from the other side (new machine with W11 pre-installed) there won't be any crud carried over, but new crud will of course be generated. Then there is the issue of restoring user data, installing and configuring user apps, etc. I have documented what it takes, and I estimate that it will take me half a day to a day, which may however also be inconsequential in the greater scheme of things.

At the present time, I am leaning towards 'everything new'. Good luck to you!
