migrate – Customers did not transfer during migration. How best to proceed?

Migration from Magento 1.9.4 --> Magento 2.4.2-p1

As far as I can tell my running of the Magento Migration tool transferred everything except the orders which we didn’t want but I just noticed we are missing Customers also. What would be the best way to proceed? Shall I re-run the Magento Migration Tool or use the

System --> Import/Export --> Export/Dataflow - Profiles 

option? If Import/Export – would it be better to use the ‘Export’ option or ‘Dataflow – Profiles’?
