Data migration
, "nearly 40 percent of data migration projects were over time, over budget, or failed entirely." As such, to achieve an effective data migration, proper planning is critical. While the specifics of a data migration plan may vary—sometimes significantly—from project to project, the computing company IBM suggests there are three main phases to most any data migration project: planning, migration, and post-migration. Each of those phases has its own steps. During planning, dependencies and requirements are analyzed, migration scenarios get developed and tested, and a project plan that incorporates the prior information is created. During the migration phase, the plan is enacted, and during post-migration, the completeness and thoroughness of the migration is validated, documented, closed out, including any necessary decommissioning of legacy systems. For applications of moderate to high complexity, these data migration phases may be repeated several times before the new system is considered to be fully validated and deployed.
UVC-based preservation
Preservation of digital resources is of a paramount importance for deposit libraries, research libraries, archives, government agencies, and actually most organizations. The dominant approach to digital preservation is migration. Migration entails making periodic transformations of archived information into new logical formats as their native formats, or the software or hardware on which they depend becomes obsolete. The notable danger of migration is data loss, and possible loss of original functionality or the ‘look and feel’ of the original format. Furthermore, digital migrations are time consuming and costly as the process requires converting the format of every document, in addition to copying converted bit streams to new media as necessary.
