Transfer logins and passwords between instances of SQL Server: sp_help_revlogin script


Transfer logins and passwords to destination server (Server B) using scripts generated on source server (Server A)


Step 1: 
Create stored procedures that will help generate necessary scripts to transfer logins and their passwords. To do so, connect to Server A using SQL Server Management Studio (SSMS) or any other client tool and run the following script:

USE [master]
  GO
  IF OBJECT_ID ('sp_hexadecimal') IS NOT NULL
  DROP PROCEDURE sp_hexadecimal
  GO
  CREATE PROCEDURE [dbo].[sp_hexadecimal]
  (
      @binvalue varbinary(256),
      @hexvalue varchar (514) OUTPUT
  )
  AS
  BEGIN
      DECLARE @charvalue varchar (514)
      DECLARE @i int
      DECLARE @length int
      DECLARE @hexstring char(16)
      SELECT @charvalue = '0x'
      SELECT @i = 1
      SELECT @length = DATALENGTH (@binvalue)
      SELECT @hexstring = '0123456789ABCDEF'

      WHILE (@i <= @length)
      BEGIN
            DECLARE @tempint int
            DECLARE @firstint int
            DECLARE @secondint int

            SELECT @tempint = CONVERT(int, SUBSTRING(@binvalue,@i,1))
            SELECT @firstint = FLOOR(@tempint/16)
            SELECT @secondint = @tempint - (@firstint*16)
            SELECT @charvalue = @charvalue + SUBSTRING(@hexstring, @firstint+1, 1) + SUBSTRING(@hexstring, @secondint+1, 1)

            SELECT @i = @i + 1
      END 
      SELECT @hexvalue = @charvalue
  END

      END
      CLOSE login_curs
      DEALLOCATE login_curs
      RETURN 0
  END

Step 2: In the SSMS query editor, select the Results to Text option.

Step 3: Run the following statement in the same or a new query window:

               EXEC sp_help_revlogin

The output script that the sp_help_revlogin stored procedure generates is the login script. This login script creates the logins that have the original Security Identifier (SID) and the original password.

Steps on the destination server (Server B)

Connect to Server B using any client tool (like SSMS) and then run the script generated in Step 4 (output of sp_helprevlogin) from Server A.

How to Check Monthly Growth of Database in SQL Server (Database Growth :last 6 month database grow)
