You can use the jadclient non-GUI client application to automate the extraction and loading of patch history, passing command line arguments after the startAppParameters argument to specify your extract and load requirements.
As patch history information is stored in compressed binary format, converting a system from ANSI to Unicode does not convert this information. This information, therefore, will not be valid when using it in a Unicode system unless you first extract the patch history from the ANSI system and load it into the Unicode system using the Replace option.
