Simple run the script and then every time SQL is restarted all your Identity columns will be reset to the latest available seed.
This script is a fix for the issue logged here. Hope it helps others like it’s helping me.
USE master;
GO
CREATE PROCEDURE sp_FixSeeds2012
AS
BEGIN
--foreach database
DECLARE @DatabaseName varchar(255)
DECLARE DatabasesCursor CURSOR READ_ONLY
FOR
SELECT name
FROM sys.databases
where name not in ('master','tempdb','model','msdb') and
sys.databases.state_desc = 'online'
OPEN DatabasesCursor
FETCH NEXT FROM DatabasesCursor
INTO @DatabaseName
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC ('USE '+@DatabaseName + '
--foreach identity column
DECLARE @tableName varchar(255)
DECLARE @columnName varchar(255)
DECLARE @schemaName varchar(255)
DECLARE IdentityColumnCursor CURSOR READ_ONLY
FOR
select TABLE_NAME , COLUMN_NAME, TABLE_SCHEMA
from INFORMATION_SCHEMA.COLUMNS
where COLUMNPROPERTY(object_id(TABLE_NAME), COLUMN_NAME,
''IsIdentity'') = 1
OPEN IdentityColumnCursor
FETCH NEXT FROM IdentityColumnCursor
INTO @tableName, @columnName, @schemaName
WHILE @@FETCH_STATUS = 0
BEGIN
print ''['+@DatabaseName+'].[''+@tableName+''].[''+
@schemaName+''].[''+@columnName+'']''
EXEC (''declare @MAX int = 0
select @MAX = max(''+@columnName+'')
from ['+@DatabaseName+'].[''+@schemaName+''].[''+@tableName+'']
if (@MAX IS NULL)
BEGIN
SET @MAX = 0
END
DBCC CHECKIDENT(['+@DatabaseName+'.''+
@schemaName+''.''+@tableName+''],RESEED,@MAX)'')
FETCH NEXT FROM IdentityColumnCursor
INTO @tableName, @columnName, @schemaName
END
CLOSE IdentityColumnCursor
DEALLOCATE IdentityColumnCursor')
FETCH NEXT FROM DatabasesCursor
INTO @DatabaseName
END
CLOSE DatabasesCursor
DEALLOCATE DatabasesCursor
END
GO
EXEC sp_configure 'show advanced options', 1 ;

RECONFIGURE

Hope this helps someone that requires this new feature to be “turned off”.
