    Hi there,

    We wanted to build a new website in top of an existent SF instance.

    Warning : The following technique supposed you are familiar with the Sitefinity database and with user-defined function in SQL (CLR). If not, do not attempt to use it, you can break everything in your Images & Documents Library !

    We renamed the files already uploaded in Images and Documents (it was quite a mess).
    To do so
      - Get a copy of the files
      - Rename it on the file system correctly
      - Batch uploaded them to the new DB with correct categories and tags.

    The problem was the upload date. How to change the original date to keep this information ?

    To do so, we used a Hash technique, based on CLR.

    Create a new SQLServerProject to deploy the user defined functions
    using System;
    using System.Data;
    using System.Data.SqlClient;
    using System.Data.SqlTypes;
    using Microsoft.SqlServer.Server;
    using System.Security.Cryptography;
    public partial class UserDefinedFunctions
        private static HashAlgorithm GetHashAlgotithm(string HashAlgorithmName)
            switch (HashAlgorithmName.ToUpperInvariant())
                case "MD5": return MD5.Create();
                case "SHA1": return SHA1.Create();
                case "SHA256": return SHA256.Create();
                default: throw new ArgumentOutOfRangeException("HashType",
    "Don't know how to create a '" + HashAlgorithmName + "' hash.");
        [Microsoft.SqlServer.Server.SqlFunction(DataAccess = DataAccessKind.None, IsDeterministic = true, SystemDataAccess = SystemDataAccessKind.None)]
        public static SqlBinary Hash(SqlBytes Source, SqlString HashAlgorithmName)
            if (Source.IsNull)
                return null;
            HashAlgorithm ha = GetHashAlgotithm(HashAlgorithmName.Value);
            SqlBinary theHash = new SqlBinary(ha.ComputeHash(Source.Stream));
            return theHash;

    Secondly, you can use this function in SQL to compute files hash and get information you need.
    select,LoweredUrl,DateCreatedLoc, dbo.HashStream(ContentValue, 'md5'as MD5
    from sitefinity.dbo.sf_CmsBinaryContent a
    left outer join sitefinity.dbo.sf_CmsContentBase b  on
    left outer join sitefinity.dbo.sf_CmsContentVersion c   on

    All you got to do is to use a inner join between databases to update the creation date.
    Et voilà !

    Thanks to Walden :
