求翻译：数据迁移部分! 如下：
测试数据,需要涉及相关的数据量的检查,业务的扩展,迁移后的检查,性能与异常的检查等,明白新老数据的变化,
要注意：
1.直接迁移后,我们仔细测试新旧字段的长度和精度是否一致,而不是长度越大,精准度越差
2.字段之间的运算,数据源的字段进行运算时得到目标字段,一般是数值型,而不是含有字母和特殊字符等,运算后的数值要准确
3.数据的关联性,测试中,应该着重关注功能的关联性,
4.新旧系统所对应的默认字段,是否还保持一致
5.还应注意日期格式的变化
6.资源信息迁移后,资源的相关属性应进行检查,比如：地域信息,银行信息,账户的消费者信息
7.迁移后,查看数据能否正确显示,链接是否有误,是否产生了垃圾数据,占用资源

Thousand trillion ether nets
Thousand trillion ether nets are establishments in the ether net standard foundation on of technique.Thousand trillion ether nets and a great deal of ether net of usages with fast ether net complete and permit, and made use of original ll technical specifications that the ether net standard rules, among them including agreement of CSMA/ CD, ether net, a works, the discharge control and 802.3 management object for defines of IEEE.Be the ether net of a constitutes the part, thousand trillion ether nets also support the discharge management technique, it guarantees the service quantity in the ether net, these techniques include the IEEE 802.1 P second floor has the initiative the class, the third layer has the initiative the class of QoS code the , special service and resourceses to reserve the agreement( RSVP).
Thousand trillion ether nets still make use of the IEEE 802.1 QVLAN support, the fourth layer filter, gigabit the third layer exchange.Thousand trillion ether nets at first are to be a kind of exchange the technique design of, adoption the fiber optic conduct and actions north bound network, used for the conjunction between the building
