OpenUpgrade v17 is not yet ready. You can check the progress here: https://github.com/OCA/OpenUpgrade/issues/4124

To migrate your Odoo 16 database to Odoo 17, ensure you have the correct setup and dependencies. Start by cloning the OpenUpgrade repository’s 17.0 branch using:

git clone --branch 17.0 https://github.com/OCA/OpenUpgrade.git /mnt/extra-addons/migration_scripts.

Next, confirm the scripts directory exists at /mnt/extra-addons/migration_scripts/openupgrade_scripts/scripts. Install the openupgradelib package using pip install openupgradelib. Update your odoo.conf file by adding:

[options] addons_path = /path_to_your_addons,/mnt/extra-addons/migration_scripts upgrade_path = /mnt/extra-addons/migration_scripts/openupgrade_scripts/scripts

Once configured, run the migration command: ./odoo-bin -d DEMO-MIGRATION -u all. If your database isn’t migrated or errors occur, check the logs by enabling debug mode in the odoo.conf file (log_level = debug). Ensure your migration scripts are complete and compatible for all modules, including custom and third-party ones. Verify data integrity post-migration by logging into the system and running consistency checks like ./odoo-bin -d DEMO-MIGRATION --check-xml. Following these steps should resolve migration issues and ensure a smooth transition to Odoo 17.

Are you able to upgrade from v16 to v17 using Open upgrade script ? Kindly update..

did you manage to solve it?

https://github.com/Viindoo/OpenUpgrade/tree/17.0

Odoo 17 is so new, that no OpenUpgrade scripts have been published yet.
There are analysis.txt files in the subdirectories of openupgrade_scripts/scripts, but no pre-*.py or post-*.py files.
If Odoo does not find those, it says that the scripts directory is not a valid upgrade directory.

So, a bit of patience will help (I'm in the same boat)
(I don't have enough karma yet to post links yet, so visit the OpenUpgrade documentation site to find out more)

you can try with bellow option

python  ./odoo-bin -d database_name --config=/odoo/odoo17_migration/odoo/debian/odoo.conf --upgrade-path=/odoo/odoo17_migration/OpenUpgrade-17.0/openupgrade_scripts/scripts -u all

Before running, Make sure config file path and configuration is updated or not
