Windows bring from HDD to SSD?

Have installed a HDD in my laptop now wants to replace the HDD with a SSD now my question is how do I get Windows 10 from the HDD to the SSD?

You can cache Windows on an external disk

On the homepage of the SSD-manufacturer there will probably be a software that you can use to clone the HDD to the SSD.
For this, of course, the SSD must first be connected together with the HDD.

You should do that, if you also want to copy boot partition and sectors. If you only want to back up the user data, then you can simply manually copy the corresponding data.
