Hi,

I try to migrate only the database from v10 to v11.

I make this steps:

1. stop the Odoo service (service odoo stop)

2. Git clone https://github.com/OCA/OpenUpgrade.git brach 11.0

3. Install the newest version of the OpenUpgradeLib (https://github.com/OCA/openupgradelib.git@master)

4.run OpenUpgrade with:

python odoo-bin -d mydatabase --update all --stop-after-init --data-dir=c:\temp -u openpg -w mypassw

5. Install all dependencies that It shows.

6 Finally after install all the dependecies it show me the error:

C:\Program Files (x86)\OpenUpgrade-11.0>python odoo-bin -d BtoBsolutions --update all --stop-after-init --data-dir=c:\temp -u openpg -w #Lmeiqupsfssa360

psycopg2.OperationalError

C:\Program Files (x86)\OpenUpgrade-11.0>

I think that probably the error is because it try to connect to a non exist database:

2020-04-07 15:15:35,642 1080 INFO ? odoo: database: default@default:default

Can you help, If I can to make a migration I want to make a tutorial step by step for all the people because the documentaion of openupgrade is not easy to understand.

Thanks in advance
