Change company, what happens to old invoices in CBSubs?

Company Alpha manage his CBSubs website till 2012. In 2013 it change name to Company Beta and also change Vat number and address. But the website is always the same. So users still have their invoices in their profile.

Now, what would report the invoices generated before company change when user go to his account an see invoices? Will it still report old company or new one?

Have you considered this case? If not, would you consider it so that old invoices will report old company or at least remove them from user view and show only in back end with old companies values?

Adjust "Show in user profile subscription tab invoices of last:" as needed within CBSubs > Settings > Display > Invoices so it'll only show the latest invoices with the changed company (set to 1 month for example) then adjust over time until you're back at 6 months of nothing but the new company name invoices. The invoices are entirely dynamic and are not stored anywhere, but are just based off other information stored in database. As the company part is just a parameter it'll update old invoices as well.
