处理办法：
Change all references of “123422720” to “56313856” ，useSsl>false，in the following files:
C:\ProgramData\VMware\VMware vCenter Converter Standalone\converter-agent.xml
C:\ProgramData\VMware\VMware vCenter Converter Standalone\converter-server.xml
C:\ProgramData\VMware\VMware vCenter Converter Standalone\converter-worker.xml
C:\Program Files (x86)\VMware\VMware vCenter Converter Standalone\converter-client.xml
Restart all VMWare vCenter Converter services.
<sslOptions>56313856</sslOptions>
<useSsl>false</useSsl>
<soapUseSSL>false</soapUseSSL>
如果保存失败，需要修改相应的目录权限，users完全控制即可：
最终迁移效果：
16G磁盘，花费20分钟。
