I've been using LineageOS for years, including for the year that I have now owned my Pixel 8 Pro. I am considering migrating, however. I'm assuming that the installation guide is written with the stock ROM in mind, and I'd like to be sure that installing GrapheneOS coming from LineageOS won't give any trouble. Specifically, I have Lineage's recovery installed. What steps should I take to avoid any snags? TIA!
