15.1.1. Step 1: Preparing the Old Certificate System

No upgrade path exists for the Registration Authority (RA) subsystem because this subsystem is no longer supported. To preserve the data in the RA subsystem, flush all data in RA request queues by processing it on the CA subsystem. Then stop the RA subsystem and database so that no further data can be gathered by it.

Stop the RA instance.

cd /usr/netscape/servers/cert-ra

./stop-cert

Stop the corresponding RA internal database instance.
```
cd /usr/netscape/servers/slapd-ra-db

./stop-slapd
```

As indicated in the server configuration table, this example assumes that a professional backup system is used to back up the entire Certificate Management System 6.1 (SP4) system, rather than the included backup facilities.

Before running the backup tools, stop all of the Certificate Management System 6.1 (SP4) servers.

Stop the OCSP, DRM, and CA instances.

cd /usr/netscape/servers/cert-ocsp

./stop-cert

cd /usr/netscape/servers/cert-drm

./stop-cert

cd /usr/netscape/servers/cert-ca

./stop-cert

Stop the CMS 6.1 (SP 4) Administration Server instance.
```
cd /usr/netscape/servers

./stop-admin
```

Stop the OCSP, DRM, and CA internal database instances.

cd /usr/netscape/servers/slapd-ocsp-db

./stop-slapd

cd /usr/netscape/servers/slapd-drm-db

./stop-slapd

cd /usr/netscape/servers/slapd-ca-db

./stop-slapd

Stop the Configuration Directory Server instance.

cd /usr/netscape/servers/slapd-ds

./stop-slapd

After stopping the server, back up the entire CMS 6.1 (SP 4) system using the external backup tool.
