Cheers everyone! So I followed exactly the Vultr knowledge base article "Migrating WordPress with rsync" and my site broke completely! White screen of death!
Sent ticket yesterday. They said I "should have backed up first" but article didnt mention that! Made test order on fresh VPS and same result. Article has dangerous gap for sites with custom wp-config paths.
Not angry, just want article fixed so next person doesnt panic! I documented everything. Can share.
