Performing archive conversions

Archive conversion is the process of reading older archives that are produced by GNU or BSD archivers, and writing new ccm_delta archives in the 7.2 or later format. The archive conversion process deletes old archive files and directories as it converts archives. Learn about some common problems and questions you might encounter while you run the archive conversion.
Here are the advantages of converted archives:

Before you start your archive conversion

Here is some information that you must know before you start your archive conversion:
  • Upgrade from Release 7.0, 7.1, or 7.1a to 7.2 or later.
  • The archive conversion is not a part of the database upgrade process.
  • You can pause the process during database backup or maintenance, even when the database is protected.
  • The process deletes old archives that were created in GNU or BSD.
  • The archive conversion runs as a low-priority background process.
  • You must run the CCM Server during the conversion.
  • Direct archive conversion from Rational® Synergy 6.5 to Rational Synergy 7.2 is not supported.
  • For the conversion, your administrator must allocate one extra backend session per database.
  • The CM administrator must run the ccm fs_check command and resolve all reported errors before and after the archive conversion.
  • You use the Web Administrator User interface to start, stop, and report on the progress of archive conversion.
