关于升级TL，请教各位大大

昨天给一台590升级OS，从5306-1升级至5308-4，我在IBM下载的包是5308TL+SP4。
    流程如下：
    将所有bff拷贝至/usr/sys/inst.images目录下，然后执行inutoc /usr/sys/inst.images
    然后smit update_all，安装完成后重启服务器，oslevel -r 却提示为5300-7？？？
    执行instfix -i|grep ML，结果如下：

All filesets for 5.3.0.0_AIX_ML were found.

All filesets for 5300-01_AIX_ML were found.

All filesets for 5300-02_AIX_ML were found.

All filesets for 5300-03_AIX_ML were found.All filesets for 5300-04_AIX_ML were found

All filesets for 5300-05_AIX_ML were found

All filesets for 5300-06_AIX_ML were found

All filesets for 5300-07_AIX_ML were found

Not all filesets for 5300-08_AIX_ML were found

               为什么呢？难道说必须把08的sp1，sp2，sp3全部打一遍？请各位大大帮忙收起
