NAS Installation - Synology DSM 7.4

Upgrade from DSM 6.4

First upgrade to DSM 7.0 through Control Panel
Go to the Synology Download Center, Select product type and Select your Synology Product, then Select DSM version currently installed and the latest DSM version offered for this product as a target DSM version
Upload the downloaded update file in Control Panel –> Update & Restore –> Manual DSM Update and start the update
The update should run without issues, after which there are a few extensions which are obsolete and which you can uninstall

KMIP for key management

Follow the guide to install KMIP on a Synology NAS server and client
What this guide does not mention is how to generate working certificates for DSM 7.4 and later, which hardened the certificate requirements, so follow my guide here:
1. The default, out-of-the-box self-signed Synology certificate will fail on DSM 7.4
2. Login to your NAS on the command line with SSH and elevate to root
3. Download Synology's official KMIP certificate script:
```
wget supweb.synology.com/support_web/kc_tool/how_to_gen_cert_for_kmip_services/gen_kmip_certs.sh
```
4. Run the script as root:
```
bash gen_kmip_certs.sh kmip_certs
```
  The second parameter kmip_certs is the name of a shared folder the script will create to store the certificates
5. Upload the generated scripts in /volume1/kmip_certs to your local computer you use to access your DSMs through your web browser
