Trying to test then install LL 3.4 on old Dell Latitude D800

If all goes well with the install and the forcepae thing will this computer update ok in future just like computers that have the right processor and DID NOT need the forcepae thing done?

That should be no problemo. You should be good to go. Don't over think  it.

I think I get what you’re saying and can try making a backup. In reality there is nothing on this computer yet other than when I go to install LL 3.4 so is there really any benefit to making a backup?

My backup post just deals with not doing rei-nstalls. You roll like you wish. I am just giving lessons in case you did not know how.
