How to move emulated SWTPM data to a new VM

I have an existing VM with an emulated TPM module. I'm trying to create a replacement VM, pointing to the same disk image that the existing VM uses, and also migrate the existing TPM module to it. Would just copying everything in /var/lib/libvirt/swtpm/<UUID> work? I did some practice runs, and it seems that virt-manager immediately starts the new VM as soon as it creates one, so I need to quickly turn it off, go look up its new UUID, and copy over the TPM files?
