I want to migrate a v4 installation to v5, but i get this error: “Undefined variable: invoices”.
Any idea where to look?
Some other questions:
What will get migrated and what not? Is there a list of the things that will not migrate, like eg. invoice templates? Do we have to recreate the invoice templates after or before the migration?
When a migration from v4 to v5 is being executed, is it possible that recurring invoices and reminders will be send from both installations? Is it save to “test” a migration?
