三步完成，sql server 2014 实例迁移

要点：

SQL Server 2012 无人值守安装（添加新实例）

http://blog.csdn.net/wangzhpwang/article/details/40739533

sql server  版本要一致
实例安装目录最好要一致
检查原sql server安装目录下log目录下的ConfigurationFile.ini获取必要参数
尝试1，尝试通过修改ConfigurationFile.ini进行静默安装
新旧服务器通过共享目录传输文件
powershell 运行策略正确设置
设置共享目录everyone完全控制权限，以便新server能访问到bak文件
在原实例master上创建备份SP,@type=1我们只演示迁移系统数据库，若要备份全部库，请在sqlcmd 调用sp_backupdatabase时改为type=0

create proc sp_backupdatabase
@bak_path nvarchar(4000)=''       --备份路径;
,@baktype int = null               --备份类型为全备,1为差异备,2为日志备份
,@type int = null                  --设置需要备份的库,0为全部库,1为系统库,2为全部用户库,3为指定库,4为排除指定库;
,@dbnames nvarchar(4000)=''        --需要备份或排除的数据库，用,隔开，当@type=3或4时生效
,@overdueDay int = null            --设置过期天数，默认天;
,@compression int =0               --是否采用sql2008的压缩备份,0为否,1为采用压缩
as
--sql server 2005/2008备份/删除过期备份T-sql 版本v1.0
/*
author:perfectaction
date  :2009.04
desc  :适用于sql2005/2008备份，自动生成库文件夹，可以自定义备份类型和备份库名等
可以自定义备份过期的天数
删除过期备份功能不会删除最后一次备份，哪怕已经过期
如果某库不再备份，那么也不会再删除之前过期的备份
如有错误请指正，谢谢.
