I see a lot of conflicting information and varying procedures in your documentation. What is the correct way to migrate a Joomla 3 site running J2Store v3 (3.3.22 Pro) to Joomla 6 running J2Commerce v6 (6.6.2)?

If possible this needs to preserve all products, categories, options, past orders, existing customers, countries, zones, measurements (lengths/weights), order statuses, email templates, configuration settings, custom fields, standard shipping methods, reporting, etc.

Is this actually necessary nowadays?

Joomla 3 + J2Store 3→ Joomla 3 + J2Store 4.0.5 → Joomla 3 + J2Store 4.0.22 → Joomla 5 + J2Commerce 4.0.22→ Joomla 6 + J2Commerce 4.0.22 → Joomla 6 + J2Commerce 6.6.2

Or is it true that a direct J2Store 3 → J2Commerce 6 migration tool is currently under development, and if so, what would be the recommended approach?

Thank in advance and kind regards,
Joris
