Obsolete Utility: Upgrade File Formats
This utility is included for backward compatibility. The utility can upgrade the format of files created in AMPS version 3.0.3 to 4.3.2 to the formats used in AMPS 5.0 and later versions.
Files created or updated by AMPS 5.0 can be successfully used in all subsequent versions of AMPS without modification. This utility is unnecessary in those cases, and should not be used for files that have already been used with 5.0 or later versions of AMPS.
For upgrading from versions 5.0.0.0 or later to this release of AMPS, amps_upgrade is not necessary.
This utility should not be used for files that have been created or modified by AMPS version 5.0.0.0 or later instances.
