Archivists' Toolkit → ArchivesSpace
Rockefeller Archive Center
An early ArchivesSpace adopter, the Rockefeller Archive Center migrated from Archivists' Toolkit, investing roughly 550 staff hours in the transition. The project was defined by aggressive pre-migration data hygiene: archivists tackled bloated extent lists and used SQL database dumps and Excel pivot tables to identify and merge thousands of duplicate subject records before running the migration tools. After that cleanup, some 3,264 accessions and 11,304 resource records moved successfully onto a locally hosted CentOS virtual machine. Frankly documented on the Center's technical blog, it underscores that migration fidelity is largely won or lost in pre-migration cleanup.
