The error message suggests that the old database was initialized with 
"German_Switzerland.1252" locale, and the new one with 
"German_Germany.1252". The new database needs to initialized with the 
same locale as the old one for pg_upgrade to work. Make sure you select 
""German_Switzerland.1252" in the PostgreSQL 13 installer.

Or you can re-initialize the datadir after installing PostgreSQL with 
something like:

initdb -D "C:/Program Files/PostgreSQL/13/data" 
--locale="German_Switzerland.1252"
