Hello,

I tried to move an openerp 7 system from an old server running on ubuntu 12.4 to a new server running on ubuntu 16.04, but it failed

• I installed the required python modules  in the new server as shown here
  

  https://doc.odoo.com/install/linux/server/

• moved the openerp folder to the new server

• made a dump of postgres in the old server

• installed postgresql and imported the dump in the new server

I run python openerp-server -c path/openerp-server.conf --db-filter=dbname

The server start with no error, but on localhost:8069 I am redirected to the admin page who asks me to create a new database, to install modules I already have installed, and I can't access the data I migrated.

What do I need to do to fix this?
