I have moved (by cloning) from an old set of servers to a new set of 3 servers (database / Odoo / Filestore). The Filestore server is mounted on the Odoo server to $HOME/.local/share/Odoo/

Issue : when I start Odoo, it keeps refering to the old Filestore server

Question : where do I need to change this ?

Error in log : 

odoo.addons.session_redis.http: HTTP sessions stored in Redis with prefix '' on :6379
