raspberry pi – Migrating NextcloudPi from SD card to USB SSD

An existing pi3-NextCloudPi is installed on a 64GB SD card: which will eventually fail from read / write cycles. Before said failure happens: The goal is to migrate the existing rpi3-NextCloudPi from its SD card to a SanDisk 1TB – External Solid State Drive – SDSSDE61-1T00-G25.

Is there a good combination of :process/ tools / command that will simplify the migration? The new configuration should have the Sandisk device running NCP & the OS, so as to avoid SD card failure.
