The first, is to read the instructions. The one thing to be aware of is you must recompile any drivers or apps you did under Buster for the new Testing kernel, particluarly if you are using Virtualbox. If you've installed dkms in Buster, it should take care of that on the first boot of Testing. Then, once all is set sources.list-wise, apt or apt-get update and apt full-grade or apt-get dist-upgrade. You should use full-upgrade or dist-upgrade for as long as Testing is testing to be sure you get everything upgraded. Once Testing becomes Stable, the use just plain upgrade. B
