Copying system DB's to a new server

    to recreate, do i need to delete the user from all the databases user entries first?

    No, leave the database users alone, the provided script will 'match up' the sql login to the database user. With the same settings as before (including password).

    Why don't you try it out on a test sql instance first? That way you can see what will happen... very straightforward.

  • cheers shabba, will give it a try now

  • error:

    Msg 208, Level 16, State 1, Procedure sp_help_revlogin_2000_to_2005, Line 19

    Invalid object name 'master.dbo.sysxlogins'.

  • ok, i now have the 2005 - 2005 script!

  • So your moving between SQL 2005 instances? My fault I attached the SQL 2000 ---> SQL 2005 script... The script below is what you need.

    --To transfer the logins and the passwords from the instance of SQL Server on server A to the instance of SQL Server on server B, follow these steps:

    --1. On server A, start SQL Server Management Studio, and then connect to the instance of SQL Server from which you moved the database.

    --2. Open a new Query Editor window, and then run the following script.

    --Note This script creates two stored procedures in the master database.

    --The two stored procedures are named the sp_hexadecimal stored procedure and the sp_help_revlogin stored procedure.

    --3. Run the following statement.

    EXEC sp_help_revlogin

    --The output script that is generated by the sp_help_revlogin stored procedure is the login script.

    --This login script creates the logins that have the original Security Identifier (SID) and the original password.

    --4. On server B, start SQL Server Management Studio, and then connect to the instance of SQL Server to which you moved the database.

    --Important Before you go to step 5, review the following information.

    --Review the following information before you run the output script on the instance on server B:

    --Review the output script carefully. If server A and server B are in different domains, you have to modify the output script.

    --Then, you have to replace the original domain name with the new domain name in the CREATE LOGIN statements. The integrated logins

    --that are granted access in the new domain do not have the same SID as the logins in the original domain.

    --Therefore, the users are orphaned from these logins. For more information about how to resolve these orphaned users,

    --click the following article number to view the article in the Microsoft Knowledge Base: 240872 (http://support.microsoft.com/kb/240872/)

    --How to resolve permission issues when you move a database between servers that are running SQL Server

    --If server A and server B are in the same domain, the same SID is used. Therefore, the users are not likely to be orphaned.

    --In the output script, the logins are created by using the encrypted password. This is because of the HASHED argument in the CREATE LOGIN statement.

    --This argument specifies that the password that is entered after the PASSWORD argument is already hashed.

    --By default, only a member of the sysadmin fixed server role can run a SELECT statement from the sys.server_principals view.

    --Unless a member of the sysadmin fixed server role grants the necessary permissions to the users, the users cannot create or run the output script.

    --The steps in this article do not transfer the default database information for a particular login.

    --This is because the default database may not always exist on server B. To define the default database for a login, use the ALTER LOGIN

    --statement by passing in the login name and the default database as arguments. The sort order of server A may be case insensitive, and

    --the sort order of server B may be case sensitive. In this case, the users must type all the letters in the passwords as uppercase letters

    --after you transfer the logins and the passwords to the instance on server B. Alternatively, the sort order of server A may be case sensitive,

    --and the sort order of server B may be case insensitive. In this case, the users cannot log in by using the logins and the passwords that

    --you transfer to the instance on server B unless one of the following conditions is true:• The original passwords contain no letters.

    --All the letters in the original passwords are uppercase letters. The sort order of both server A and server B may be case sensitive,

    --or the sort order of both server A and server B may be case insensitive. In these cases, the users do not experience a problem.

    --A login that already is in the instance on server B may have a name that is the same as a name in the output script. In this case,

    --you receive the following error message when you run the output script on the instance on server B: Msg 15025, Level 16, State 1, Line 1

    --The server principal 'MyLogin' already exists. Similarly, a login that already is in the instance on server B may have a SID that is

    --the same as a SID in the output script. In this case, you receive the following error message when you run the output script on the

    --instance on server B: Msg 15433, Level 16, State 1, Line 1 Supplied parameter sid is in use. Therefore, you must do the following:

    --A. Review the output script carefully.

    --B. Examine the contents of the sys.server_principals view in the instance on server B.

    --C. Address these error messages accordingly.

    --In SQL Server 2005, the SID for a login is used as the basis for implementing database-level access.

    --A login may have two different SIDs in two different databases on a server. In this case, the login can only access the database

    --that has the SID that matches the SID in the sys.server_principals view. This problem may occur if the two databases are consolidated

    --from two different servers. To resolve this problem, manually remove the login from the database that has a SID mismatch by using the

    --DROP USER statement. Then, add the login again by using the CREATE USER statement.

    --5. Open a new Query Editor window, and then run the output script that is generated in step 3.

  • just before i do (overly cautious again)

    this will not make any changes to the live system? - just produces a script that i can run on test and recreate the logins

  • Yes, that's right.

  • Excellant!

    works a treat!

    cheers Shabba

  • fantastic... told you it was easy! 😉

    Have fun
