A system and method are described for Universal Description Discovery and Integration (UDDI) data migration exporting existing UDDI V3 data from a UDDI V3 compliant repository (a source repository) and importing this data into another UDDI V3 compliant repository (a destination repository). The data from the source repository is migrated into the destination repository and remains in the custody of the destination repository. The method preserves the user name and entity key associated with the data during the process. If that is not possible, the method generates new user names and/or entity keys and creates a mapping between the original and the generated user names and/or keys in order to dispatch the requests properly during runtime. Source repository is required to support the mandatory UDDI v3 APIs and may need to support the optional Security API Set. Destination repository is required to support the mandatory UDDI v3 API and the optional Security API Set. Other optional APIs (as replication and subscription for example) are not required to be supported by any of the repositories.
