A pack file is also useful when you upgrade from one release of Rational® Synergy to the next. You can pack a database using an older release and unpack it under a new release as part of the upgrade process.
You can move the pack file to different machines, and typically to different architectures. You can move a pack file from one UNIX® platform to another UNIX platform, or from UNIX to Windows®, but not from Windows to UNIX.
