Migration of dynamic model files
The dynamic model files
(files with .mdl and .ldm extension) are backed up in the .migrate.bkp.<version>
directory. These files are not considered by sm_migrate utility for
merging. Remove the .ldm file from the local directory of the new
installation. Recompile the .mdl file before it is used in the new
installation. A new .ldm file will be generated once you recompile
the .mdl file.
The explains the concepts and
methods of dynamic modeling.
