Hi, you can write your code to open another wizard from a wizard like this:

In xml:

<record id="product_wizard" model="ir.ui.view">
        <field name="name">first.wizard.form</field>
        <field name="type">form</field>
        <field name="model">sample.wizard</field>
        <field name="arch" type="xml">
            <form string="---------" version="7.0">
             ------------------------

            -------------------------

<button name="second_wizard" colspan="1" string="Go to Second Wizard" type="object"  context="{'default_id':active_id,---------}"/>
             
            </form>
        </field>
    </record>

        <record model="ir.actions.act_window" id="action_add_package_product_form">
            <field name="name">First Wizard</field>
            <field name="res_model">sample.wizard</field>
            <field name="view_type">form</field>
            <field name="view_mode">form</field>
            <field name="view_id" ref="product_wizard" />
            <field name="context">{........}</field>
            <field name="target">new</field>
        </record>

In py file:

    def second_wizard(self, cr, uid, ids, context):
  --------------------

   --------------
        return {
            'name': "Second Wizard " ,
            'view_type': 'form',
            'view_mode': 'form',
            'view_id': False,
            'res_model': 'second.wizard',
            'src_model': 'first.wizard',
            'type': 'ir.actions.act_window',
            'context': context,
            'target': 'new',
        }

( Note : Like the first.wizard, you should create the second.wizard in both py and xml )
