 <datasource>/home/ubuntu/sit/mapserver/tif/213130.tif</datasource>
            <layername>213130</layername>
            <srs>
 ...

            <customproperties/>
            <provider></provider>

 Solved by replacing all occurences of

 with

 <provider>gdal</provider>

 Now old 1.6 project with raster are opened with success.

 Thank you
