information for update to Joomla 4.4.1 and Jshop 5.5.2

HI!
is this the procedure to upgrade from J3 to J4.4.1 and to Joomshopping 5.5.2?
locally on Xampp PHP 8.1 (php recommended by Joomla):
I upgrade to Joomla 4.4
I update Joomshopping to 5.2.2
I update all modules and addons

I don't delete anything and just update?
Will PHP 8.1 work with all these modules/addons written below?
Any other special precautions?

-Category/product as catalog
