Last edit of an order : stored in "mdate" from the table "jos_vm_orders"?

[Mister Paul]

Hi,

I am migrating an old Joomla / Virtuemart site and I'd need to migrate the last database content.
For now few things can change since the new site will be turned on :
users, customers, orders (new and edited),...

My question is:
does the column "mdate" from the table "jos_vm_orders" correspond to the date of any modification made in an order by user or manager (like Status modification I suppose)?

Thanks for your help
Paul
