I'm about to run the Magento Migration Tool and it says in the documentation to run it against a clone and not a real production website. Is that really necessary if we don't mind the potential downtime? (I guess we need to switch our Magento 1 stores to maintenance mode before starting the migration to Magento 2?)
What are the real chances of damage being done to the Magento 1 store when running the Magento Migration tool? Doesn't it just copy files?
We have Jetbackups which should allow us to do a full restore within an hour. If there is no real danger of damage to the Magento 1 store, I might just take my chances and then do the restore if needs to be.
