Does recommend work with Both M1 and M2 after successful Data migration?

We are developing Magento 2.3.3 website, still Magento 1.9 site live. After successful Data migration using data migration tool from m1 to m2, still m1 live upto 5 months as well as working with magento 2.3.3.

Is my workout recommend?

@kingstoncole_ki Test the site made in magento 2 and try to launch it as the only live site as if you continue to use the magento 1 website then many new customers and orders may come in that website and when magento stops supporting magento 1 then you have to switch to magento 2.

In that case you again have to migrate the whole data and it would be somewhat hectic.

Thanks
