Database Migration Step by Step in SQL Server

Database Migration Step by Step in SQL Server 2005 to SQL Server 2008.

Users list:
Username:TestA
Password:TestA  (db_datareader Permission)

Username:TestB
Password:123456  (db_datareader & db_datawriter Permission)

Username:TestSysadmin
Password:654321(SysAdmin)

Databases Involved this Migration:

Testdb
northwind
MIG05TO12

Database Location on Disk:(File created from SQL 2005)



Users loggged in SQL 2005:



User info in SQL 2005 of master and db

USE MASTER
GO 
SELECT name as SQLServerLogIn,SID as SQLServerSID FROM sys.syslogins
WHERE [name] = 'TestA'
GO

USE Testdb
GO 
SELECT name DataBaseID,SID as DatabaseSID FROM sysusers
WHERE [name] = 'TestA'


Northwind on new SQL 2008


To restore northwind db on SQL 2008






When click on option button and elipses button on restore db kindly review sp_helpdb 'Northwind05to08' to select correct file or not(when u use restore in SQL05)







sp_change_users_login 'Report'


kindly refer for script/to get script

Run the following statement (SQL 2005) (Source)

EXEC sp_help_revlogin




Paste it to Destination server (SQL 2008)

-- Login: TestA
CREATE LOGIN [TestA] WITH PASSWORD = 0x0100C7FE879D66EB75B7310394F7A23B3E6573F172088F9FA5BA HASHED, SID = 0x2DAB4231E8C7DC4FB2008B0D5C96E492, DEFAULT_DATABASE = [master], CHECK_POLICY = OFF, CHECK_EXPIRATION = OFF

-- Login: TestB
CREATE LOGIN [TestB] WITH PASSWORD = 0x0100675093167881BF8D70EF7376179AEFBC73520AF60E536142 HASHED, SID = 0x7027EBCE66734441B8C2641D4EF05607, DEFAULT_DATABASE = [master], CHECK_POLICY = OFF, CHECK_EXPIRATION = OFF

-- Login: TestSysadmin
CREATE LOGIN [TestSysadmin] WITH PASSWORD = 0x01006777AC698EE0D7A963E3B184780B3A31FD629D9EB58D2AF0 HASHED, SID = 0xDDEC323CF5B2DE4584E9B81265B3678A, DEFAULT_DATABASE = [master], CHECK_POLICY = OFF, CHECK_EXPIRATION = OFF


Now u can run 

sp_change_users_login @Action='update_one', @UserNamePattern='TestA', @LoginName='TestA'

sp_change_users_login @Action='update_one', @UserNamePattern='TestB', @LoginName='TestB'

It solves orphan users So u can run above statements.

now u can run 

sp_change_users_login 'report'
or
below script again we already checked earlier as show below


Now u can see all SQL ServerSID & DatabaseSID are same.

also u can check is it solve orphan users or not

Kindly u can run as see below






Thats All. 

Happy Blogging and SQLing
