Add to pool adds a vdev. You want to add to a vdev.
Storage > Pool > Status > (drive) > Extend

Is this possible when i have one disk pool with data in it and i want to make it mirror, is configuration and data safe ?
Yes, it is safe. After success, get a new system configuration download.
Meaning that data will not be lost from the disk that will be expanded to mirror ?
If you are doing it correctly through the GUI, all it does to a single disk pool is add the second disk as a mirror and copy data from the first disk.
If you are worried, set up TrueNAS in a Virtual environment along with a few virtual drives and play with the software until you are comfortable adding and removing drives from a Mirror VDEV and/or the single stripe VDEV to create a Mirror VDEV
From GUI, choose Storage, Manage Devices, Choose your single disk and then the Extend button on right. Choose your second disk, hit Extend button and it adds it as a mirror to the first disk and copies data.
