[多选题]SSS扩容过程中容灾配合操作描述正确的有（ ）。
Which of the following statements are correct about disaster-tolerance operations during SSS expansion? ( )
A.一般情况下扩容不推荐容灾方式扩容，因为已有的容量已经达到系统极限，容灾方式对另一侧的系统是个考验
Usually, it is not recommended t apply the disaster-tolerance mode in expansion. This is because the existing capacity has reached system limits, so the disaster-tolerance mode is a test upon the system on the other side.
B.扩容过程中在数据配置完成后重启单板过程中会发生容灾倒换，部分用户由于刷新注册到期后无法进行正常刷新会容灾到备用局点
During the expansion process, disaster-tolerance switchover will occur when the board is restarted after data configurations are completed. When refresh registration of some users is expired, these users cannot be refreshed normally, so they will be switched to the standby office for disaster-tolerance.
C.业务测试验证前，需要将邻接网元的容灾状态倒回，以让用户回到扩容的SSS上进行注册
Before service test verification, we need to switch back the disaster-tolerance status of adjacent NEs, so that users are registered on the disaster-tolerance SSS.
D.在SSS扩容数据配置完成后，应该将相关网元的自动容灾切换开关关闭，防止在扩容网元重启过程中用户来回切换，也预防在扩容异常的情况下系统的震荡
After data configurations in SSS expansion are completed, we should disable the automatic disaster-tolerance switchover function on related NEs, so as to avoid back-and-force switchover of users when the expanded NE is restarted, and also avoid system oscillation when an error occurs during expansion.
