MES升级的一个重要特性是不改变系统序列号。
An important feature of an MES upgrade is that the systems serial number does not change.
在转移之前，从aix运行lsconf命令并记住系统序列号。
Prior to the migration, run the lsconf command from AIX, and note the system serial number.
我也知道系统序列号肯定不会变，所以不会出现由于系统ID变化导致的应用程序许可证问题。
I also knew that the system serial number was guaranteed not to change, so I wasn't going to have application licensing problems because the system ID had changed.
