How do I migrate my phone contacts to my iPad?

Whatever account they are stored in on the phone , eg Google or Microsoft, then add the same account to the ipad.
If it is iCloud and both devices are on your same iCloud account, then it should be automatic.
If your contacts are stored on the phone only then it will not be easy. Consider using iCloud.
