When you get the drive, format to APFS. This is required to get the drive to appear in CCC.
Make a CCC task and for Source choose your existing installation.
For Destination choose the drive and Legacy Bootable Backup Assistant. This will prompt to erase the new drive which is required. CCC will engage Apple's APFS Replication Utility which will clone the entire source installation to the destination, while arranging the Signed System Volume (SSV) which Apple requires. Only Apple's utility has the capability to handle the crypto.
The clone operation will proceed. If it fails with an obscure error, this is a sign that there are hard errors on the source drive. The APFS Replication Utility cannot tolerate any I/O error as it imperils the crypto for the SSV. If this unlikely even occurs, you will need to reinstall macOS on the destination and use Migration Assistant.
Once the clone is done, you need to add your OC config to the EFI folder on the new drive, assuming you want an all-in-one installation.
Best to you
