No, it is not. It can work if you know really well what you are doing
(but is very likely to cause major problems when doing an LTS->LTS
jump), but it is not officially supported and receives little to no
testing

These are the mechanics, for *any* OS installation/upgrade: read release
notes, ponder, follow instructions.
