upgrade ssd optiplex 3070SFF

I have a Dell optiplex 3070SFF. Which has a NVMe SSD Western Digital 128gb drive with Windows 11 on it I bought a Crucial T500 NVMe drive (500gb) to upgrade this machine along with an extra 8gb of RAM. I used a USB adaptor to install the T500 SSD in and downloaded the Cloning software Acronis from the crucial site However there is no way I can get the WD drive to clone to the T500. I have spent hours on the Crucial chat speaking to different people trying all sorts of suggestions and getting nowhere. I am now at the stage where I am about to return this drive unless someone can come up with a solution or suggest an alternative  drive that will work in the delll NVMe slot and one I can copy the WD drive to
