There are many automated data migration tool in the market but I highly recommend you to use this service called litexxtension. It's quite a great product that I've used– user81967Commented Nov 15, 2019 at 4:11

Always use a fresh database to migrate from Magento 1 to Magento 2.
If you migrate it with already existing database then highly probability to conflict database table id and it is always through an error.
You can not migrate 100% data in the existing database.
You can do the delta migration process with the same M2 database after the first migration process.

Both are the same process. but delta migration is when you live your M2 instance then you get a new order, a product from M1 using delta migration. Commented Nov 12, 2019 at 12:19
You can do the delta migration process with the same M2 database after the first migration process.
The first migration process is done with bin/magento migrate:data CLI command
The delta migration is done using bin/magento migrate:delta CLI command
