We upgraded ours from 9.3 -> 10 in summer 2018, with quite a lot of custom code, functions, extensions and it went absolutely fine, we were able to have the server up in some minutes.
However, you should EXTREMELY test everything before the final upgrade, and I dont mean only the actual app (and all kinds of db related code, queries, data sources, drivers, etc), but the actual
pg_upgrade as well. You don't wanna be left compiling and upgrading some extension during the upgrade phase. All should be tested and documented (I wouldn't say automated but you get the point)
beforehand.
