Caché Upgrade Checklists - InterSystems Documentation

1General Upgrade InformationBackgroundCaché version 5.1 was a significant improvement in functionality and security over its predecessors. In making this advance,InterSystems goal was to provide a compatible evolutionary path forward whenever possible. However, many of the features,such as the System Management Portal, replaced functions in previous releases with new mechanisms. Furthermore, theaddition of the new security features required a partial redesign and reorganization of the underlying system. These introducedincompatibilities with previous versions of Caché.Documenting these changes in a single place proved useful and has been continued for subsequent releases of Caché.OrganizationThe major divisions of this document represent the significant changes from the prior release, starting with the currentversion. Within each release the material is organized by whether it primarily affects administrators, operators, or applicationdesigners/developers of existing systems. The divisions are not meant to be exclusive; many of the items of interest toadministrators also affect application developers. Readers are encouraged to review all pertinent material in other sections.1.1 Upgrading Caché1.1.1 Upgrading from Field Test VersionsCAUTION:InterSystems does not support an upgrade from any Field Test version to another Field Test version, norfrom a Field Test version to an officially released version.
