##### SUMMARY

Can you tell me if it is possible to add ipv6 to a deployed Shared network in an advanced core zone if the fields related to ipv6 were not filled in during its creation. Perhaps this can be achieved by editing the database? The important point is that there are already deployed vms in the network and their operability should not be disturbed.

先檢視 CloudStack 對進階核心區域中 Shared networks 的 IPv6 欄位處理方式，以及變更會如何影響已部署的 VMs。確認是否存在不會中斷這些 VMs 的受支援途徑；完成的標準是記錄該程序或確認此限制。
