The amps_upgrade tool is provided for versions of AMPS 5.0 and earlier. The amps_upgrade tool updates the format of the data in the files that AMPS maintains. If there has been no version change to the format of the data, it is not necessary to run the tool to upgrade an AMPS instance.
Notice that, while this chart describes the format of the files, AMPS versions may also change or extend the content of the files. In these cases, AMPS is guaranteed to be forward-compatible. That is, a given version of AMPS can process a file of the same file format version created on an earlier version of AMPS. However, later versions of AMPS may include changes in the content of the file that are not recognized by earlier versions of AMPS. This means that downgrading a file between major/minor versions of AMPS is not supported.
The contents of AMPS files are not guaranteed to be backward compatible across changes to the major or minor version number. That is, while an AMPS instance of version X.4 can successfully load a SOW file created by version X.3, the version X.3 instance may not be able to process a file created or updated by the X.4 version.
Contact 60East support for guidance if you intend to downgrade an instance of AMPS to an earlier version.
