7.6.3.1. Case I: Security Databases to Security Databases Migration

Remove all the security databases in the new Certificate System which will receive migrated data.
```
rm /var/lib/instance_ID/alias/cert8.db

rm /var/lib/instance_ID/alias/key3.db
```

Copy the certificate and key security databases from the old server to the new server.

cp old_server_root/alias/cert-old_OCSP_instance-cert8.db 
/var/lib/instance_ID/alias/cert8.db

cp old_server_root/alias/cert-old_OCSP_instance-key3.db 
/var/lib/instance_ID/alias/key3.db

Log into the new server as the Certificate System user, and open the Certificate System alias/ directory.
```
cd /var/lib/instance_ID/alias/
```
Log in as root, and set the file user and group to the Certificate System user and group.
```
su

chown user:group cert8.db

chown user:group key3.db
```
Log out as root. As the Certificate System user, change the permissions on the files.
```
chmod 00600 cert8.db

chmod 00600 key3.db
```

List the certificates in the security databases using the certutil command. In this example, -L lists the certificates.

certutil -L -d . 

Server-Cert cert-old_OCSP_instance cu,cu,cu
caSigningCert cert-old_OCSP_instance CT,c,
ocspSigningCert cert-old_OCSP_instance cu,cu,cu

Open the CS.cfg configuration file.

cd /var/lib/instance_ID/conf/

vi CS.cfg

Edit the ocsp.signing.certnickname attribute to reflect the new subsystem information.
```
ocsp.signing.certnickname=ocspSigningCert cert-old_OCSP_instance
```
NOTE

>The caSigningCert is not referenced in the CS.cfg file.
In the same directory, edit the serverCertNick.conf file to contain the old certificate nickname. For example:
```
vi serverCertNick.conf

Server-Cert cert-old_OCSP_instance
```
