Export invoice model from V4 to V5?

Hello.
Is there a way to refund or export my personal invoice model from the V4 and use it with V5 ?

Hi,

To upgrade from v4 you need to install v5 as a separate app and then use the migration tool in the latest version of v4 on Settings > Account Management.

Does that answer your question?

does the migration from v4 to v5 will take all the invoices models previously made in v4 and make it available into V5 ?

Yes, that is correct
