Script deployment to multiple servers

I use the following script in order to deploy a T-SQL script to multiple servers:

SET NOCOUNT ON
GO

DECLARE @object_name SYSNAME                      
DECLARE @cmdstr NVARCHAR(300)                        
DECLARE @servername SYSNAME                             
DECLARE @instancename SYSNAME                      
DECLARE @inputfile NVARCHAR(128)                      
DECLARE @outputfile NVARCHAR(128)                     
DECLARE @prodsrvs TABLE(srvname sysname)
                
DECLARE crs_srv CURSOR
LOCAL 
FAST_FORWARD
READ_ONLY
FOR 
  SELECT srvname
  FROM @prodsrvs

INSERT INTO @prodsrvs(srvname)
SELECT 'Server-01'
UNION ALL SELECT 'Server-02'
UNION ALL SELECT 'Server-03'
UNION ALL SELECT 'Server-04'

OPEN crs_srv
FETCH NEXT FROM crs_srv INTO @servername

WHILE @@FETCH_STATUS=0                   
BEGIN

SELECT @cmdstr = 'sqlcmd -S ' + @servername + ' -i "\\PathToScript\Script.sql" -o "\\PathToScript\script_output.txt" '

EXEC dbo.xp_cmdshell @cmdstr
PRINT(@servername)

WAITFOR DELAY '00:00:05'

FETCH NEXT FROM crs_srv INTO @servername               
END

CLOSE crs_srv
DEALLOCATE crs_srv

SET NOCOUNT OFF
GO

Detach/Attach VS ALTER DATABASE MODIFY FILE

It's not a news that Detach/Attach method for moving database affects different aspects. When a read-only database is detached and then reattached, the backup information about the current differential base is lost. Service Broker gets disabled and it requires exclusive access to re-enable it back. TRUSTWORTHY also get disabled during detach/attach operation.
So in order not to get trapped it's better to use ALTER DATABASE MODIFY FILE command. Below script generated ALTER DATABASE commands, you just need to enter your database name and new locations for data and log files:

DECLARE @NewDataFolder nvarchar(1000);
DECLARE @NewLogFolder nvarchar(1000);
DECLARE @FileTable table (lkey int identity (1,1) primary key, [name]nvarchar(100), physical_name nvarchar(1000), [type] int );
DECLARE @CmdTable table (command nvarchar(1000));
DECLARE @sql nvarchar(4000);
DECLARE @count int;
DECLARE @RowNum int;
DECLARE @DbName nvarchar(100);
DECLARE @OldPath nvarchar(1000);
DECLARE @Type int;
DECLARE @LogicalName nvarchar(100);
DECLARE @ParmDefinition nvarchar(1000);
DECLARE @FileName nvarchar(100);
DECLARE @NewPath nvarchar(1000);

--Make sure that @NewDataFolder and @NewLogFolder has '\' at the end
SET @DbName = 'YourDBName'
SET @NewDataFolder = 'C:\SQLData\'
SET @NewLogFolder = 'C:\SQLLog\'

SET @sql = 'select name, physical_name, type from  ' + @DbName + '.sys.database_files'
INSERT INTO @FileTable
EXEC sp_executesql @sql 

WHILE @@rowcount > 0    
 BEGIN
  
  SET @OldPath = (SELECT TOP 1 physical_name  FROM @FileTable)
  SET @Type = (SELECT TOP 1 [type]  FROM @FileTable)
  SET @LogicalName = (SELECT TOP 1 [name]  FROM @FileTable)
  SET @FileName = (SELECT REVERSE(SUBSTRING(REVERSE(@OldPath), 0, CHARINDEX('\', REVERSE(@OldPath), 1))))
  IF @type = 0
  BEGIN
   SET @NewPath = @NewDataFolder + @FileName
  END
  ELSE
  BEGIN
   SET @NewPath = @NewLogFolder + @FileName
  END
  SET @sql = 'ALTER DATABASE ' + @DbName + ' MODIFY FILE (NAME = ' + @LogicalName + ', FILENAME = ''' + @NewPath   + ''')'
  INSERT INTO @CmdTable SELECT @sql 
  DELETE FROM @FileTable WHERE [name] = @LogicalName 
END 
SELECT * FROM @CmdTable
