We have started work to make the switch to Lightning and have come across an issue we can't find the answer to.

If there was an existing process scheduled (from classic) to send emails using a VF email template in a scheduled batch, rather than through UI, wouldn't these continue to run, even if all users are using Lightning?

I have a sandbox switched to Lightning and I have tested and it worked. So I believe the answer to that question is yes, but I wanted to try and get confirmation since everything I read says VF email templates do not work in Lightning. The emails sent are going to our customer community members. They are order acknowledgments and shipment notifications. So it is critical to our org that these go successfully. 

Thank you,
