Hello,

I assume what you mean by "migrate" is by migrating the machine and not the Odoo version, no?

The best way might be just simply install the Odoo in docker (lets say you are using Odoo version 15). After that, from your ubuntu vm you can access www.yourodoolink.com/web/database/manager and download your database in zip format from there.

After that, access your www.yourcontainer.com/web/database/manager and restore your database from there. This way it will preserve all user data in the new container.

Best regards,
