Where is the data held for the customised views?

-- HikaShop version -- : 4.7.4
-- Joomla version -- : Latest
-- PHP version -- : 7.4.33
-- Browser(s) name and version -- : All
-- Error-message(debug-mod must be tuned on) -- : No error

I want to dump selective tables, i.e characteristics, product, orders etc, to my Joomla4 version of Hikashop, what I don't want to do is copy over the old views as this would wipe out some of my fixes/changes in the Joomla4 version before I put it live and replace the old Joomla3. So my question is where is the data held for customised views?

Thanks in advance,
Ian
