We upgraded ours from 9.3 -> 10 in summer 2018, with quite a lot of custom code, functions, extensions and it went
absolutelyfine, 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
kindsof 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
betested and documented (I wouldn't say automated but you get the point) 
 
beforehand.
