把SQL SERVER里面的用户权限做迁移，从A迁移到B，当时就挑起兴趣了，之前都是做过数据库的迁移，就是数据库分离，然后附加！安全一点的就是备份，恢复！
用户安全性的迁移貌似没做过，在网上Google了一下，在这里记录了一些信息，列举如下：
环境介绍”
Server Name: SCSQL,Contoso.com IP:192.168.100.125
2. Server Name: SQL2. Contoso.com IP:192.168.100.125
迁移数据库对象： database: SMS_GDA
步骤如下：
1. 在SCSQL.CONTOSO.COM下备份数据库SMS_GDA（完整备份）到 D:\bak\SMS_GDA.BAK,
2. 把SMS_GDA.BAK,复制到SQL2.CONTOSO.COM上，恢复数据库SMS_GDA.BAK
3. 在SCSQL.contoso.com上执行以下语句:

4. 在SCSQL.CONTOSO.COM下，查看master数据库的存储过程，会多了2个sp.help.revlogin, sp_hexadecimal
5. 再次执行代码：
EXEC sp_help_revlogin
6. 复制执行代码后的结果
7.在 SQL2.CONTOSO.COM 查询分析器上执行，粘贴过来的代码
其实大家从图中已经可以看出来，在SCSQL.CONTOSO.COM的用户都过来了，语句中出错的是已经存在的用户，大家可以在事后去检查一下，并去验证登录请求
