由于在NBU6.0中有了一个EMM（Enterprise Media Manager）的概念，NBU的升级不像以前那么简单了。需要将globDB,volDB，MediaDM等一些信息导入EMM的数据库中。
升级需要按照下面的顺序作才行：
1. Global Device Host
2. Master server
3. Volume Database Host
4. Media servers
5. Clients
NBU6.0支持混合环境，但是media server的版本不能低于NBU5.X。Client的版本不能低于NBU4.5。NBU6.0只支持NBU5.X升级到NBU6.0。如果想使用NBU4.5 or NBU3.X升级到NBU6.0，需要先升级到NBU5.X。
假设目前我们的环境是：
Master server: host1, NBU5.1+MP2, Solaris 9
Media server: host2, NBU5.1+MP2, Win2000 server+SP4.
Client: host3, NBU5.1, Solaris 9
Client: host4, NBU5.1, Win2000 server+SP4
我们要将Master server and Media server从5.1升级到6.0。
升级的步骤如下：
1. 升级Master Server
a) 备份catalog（注意要加上media server的路径。。。）, 最好备两份一个用磁带，一个备份到硬盘上面。
b) 卸载NBU的包，卸载的时候注意“Are you doing this pkgrm as a step in an upgrade process? [y,n,?,q] “的提示，选择y
Pkgrm VRTSnetbp
c) 安装PBX 和NBU6.0, 详情请看<< NetBackup6.0 Beta3 For Unix安装步骤>>
d) 注意当安装教本询问是否有其他Media server的时候，一定要将以有的media server名字加上，否则在以后添加的时候过程比较麻烦。
e) 注意提示的EMM server的名字，最好就用master server。NBU6.0支持EMM server装在其他Media server上，这中情况不再这次的讨论范围。
f) 检查包是否装上
# pkginfo |grep -i vrts
system VRTSicsco VERITAS Infrastructure Core Services Common
application VRTSnetbp VERITAS NetBackup and Media Manager
system VRTSpbx VERITAS Private Branch Exchange
g) 用bpps –x检查一下进程时候都起来了。
h) 运行如下命令，再运行的时候要确认其他media server的进程都再。

k) jnbSA进入java界面，界面和原来的基本相同，测试一下本机的备份，看是否成功。
如果成功开始升级media server. 没成功的话只能卸了重作吧。。。
