This is a pretty useful tool to update Odoo installations after tax reforms on the official charts of accounts, or to apply fixes performed on the chart template. The wizard: * Allows the user to compare a chart and a template showing differences on accounts, taxes, tax codes and fiscal positions. * It may create the new account, taxes, tax codes and fiscal positions detected on the template. * It can also update (overwrite) the accounts, taxes, tax codes and fiscal positions that got modified on the template.
