7.4.2.1. 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_DRM_instance-cert7.db 
/var/lib/instance_ID/alias/cert7.db

cp old_server_root/alias/cert-old_DRM_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 cert7.db

chown user:group key3.db
```
Log out as root. As the Certificate System user, set the file permissions.
```
chmod 00600 cert7.db

chmod 00600 key3.db
```
Use the certutil tool to list all of the old Certificate System certificates. In this example, -L lists the certificates, and -X forces them to be read/write.
```
certutil -L -X -d . 

Server-Cert cert-old_DRM_instance cu,cu,cu 
caSigningCert cert-old_DRM_instance CT,c, 
kraStorageCert cert-old_DRM_instance u,u,u 
kraTransportCert cert-old_DRM_instance u,u,u
```
NOTE

The certificate database is automatically converted from cert7.db to cert8.db.
Remove the cert7.db database from the alias/ directory.
```
rm cert7.db
```

Open the CS.cfg configuration file.

cd /var/lib/instance_ID/conf/

vi CS.cfg

Edit the kra.storageUnit.nickname and kra.transportUnit.nickname attributes to reflect the new DRM information.
```
kra.storageUnit.nickname=
 kraStorageCert cert-old_DRM_instance
kra.transportUnit.nickname=
 kraTransportCert cert-old_DRM_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_DRM_instance
```
