SF control file (home pubset)

The SF control file of HSMS can always be continued. An SF control file that was created by a lower HSMS version can always be read and continued by a higher HSMS version. The file is continued automatically on generation of the subsystem.

The SF control file, however, is not downwardly compatible. An SF control file that was created by a higher HSMS version cannot be read by a lower HSMS version. You are therefore strongly advised to make a copy of the current SF control file before a new HSMS version is started. The copy of the control file is very important in the event of a downgrade.
