Migration from Hummingbird DM to Oracle
EUMETSAT - Client Profile
The European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) supplies weather and climate-related satellite data, images and products to the National Meteorological Services of our Member States in Europe, and other users worldwide.
The expertise and commitment demonstrated by Proventeq was key in delivering this challenging project. They responded quickly to any issue or new request in a very pragmatic and flexible way, always working towards solutions fulfilling our needs.
Case Study Overview
EUMETSAT had been using Hummingbird document management (HDM) to manage their strict document policies and security. however, their corporate strategy warranted a move to Oracle UCM 11g (UCM). Since the Hummingbird DM application was customised for the organisation, moving data to UCM posed real challenges.
The Complexities Of Migrating From Hummingbird DM To Oracle
- Around half a million documents with multiple revisions had to be migrated with all the attributes, relations, attachments, access rights and audit history.
- Other data like users, groups, personal workspaces and saved searches had to be migrated.
- The architecture of HDM and UCM are natively different, which meant various types of complex mappings were required to move the documents.
- HDM uses virtual folders and virtual links which introduced challenges in mapping multiple parents in the information hierarchy.
- Certain advanced cross-referencing between content were not natively supported in UCM.
- Permission structure in HDM did not have a straightforward mapping on to the UCM permission structure or its permission inheritance.
- Data was constantly changing.
Solving EUMETSAT’ Unique Challenges
Proventeq worked closely with their UCM implementation partner, Infomentum, to provide the client with an efficient migration solution.
Proventeq’s Migration Accelerator was used to migrate content into the new target SharePoint environment.
Our Discovery tool helped to analyse all available documents in Hummingbird, enabling the identification of any inconsistencies in metadata, content and permission. Numerous reports were generated to identify data corruption and distribution of relevant metadata.
A proof of concept was successfully executed on a sample data set to highlight the benefits of automated migration. Our expert migration consultants then defined a migration strategy to handle the complexity of numerous exception cases introduced after an upgrade process.
All challenges pertaining to differences in the fundamental architecture were resolved during the pilot migration phases.
A ‘Delta plan’ was put in place to enable the organisation to function as normal while the migration was still in process.
