Adding to what @jswim788 said, if you’ve still got a backup of your old installation then you can copy the security key from your ZWave controller in PaperUI and paste it into your new installation. Then you’ll need to reinitialize your lock and garage-door controller.
For your Sensor 7, you might need to wake it up quite a few times to get it working. However, if you change your security key then you’ll have to remove and re-include it.
Note that secure inclusion increases Z-Wave traffic significantly, which could cause network issues and will impact battery life. For these reasons, some folks recommend only using it for devices that can unlock your house, and leave everything else insecure.
