first I thought it's a good idea to clarify for all the people that are just starting out to follow the F&L guide that as of 09.05.2018 MO is no longer able to download mods directly from Nexus. It is to be replaced by MO2, so new users are advised to start out by installing MO2 outright, ignoring what the guide says (it's support is discontinued anyway).
People who already have followed F&L should migrate to MO2 in order to keep with the latest mod versions. And here is my question: can anyone provide a guide how to do it? Can I migrate my Mods folder, load order and saved profiles with minimal effort? How can I modify my other executables (Wrye Bash, Xedit, etc.) to start in MO2? Do the command line for that change?
