Legacy Data• Legacy programs = legacy data

– C130 (1950’s)– C5 (1960’s)– F16 (1970’s)– F22 (1980’s)– F35 (1990’s -> 21st Century)– Advanced Development Programs (19?? – 20??)

• Data in many forms– Vellum, physical media, etc– 2D CAD (CADAM, CATIA V2/V3/V4/V5)– 3D Surface data (CATIA V2/V3/V4/V5)– 3D solids (CATIA V3/V4/V5)– Full 3D definition

• Supplier data– Another story for another time

Legacy Data Management Systems

• Physical Media – Vaults, locked rooms, cabinets, environmentally controlled atmospheres– Drawings and BOM’s

• 2D CAD– File structure based release and storage mechanisms– Later -> promotion to database solutions (some

software required to “connect the dots”)• Early 3D CAD

– File structure based release and storage mechanisms– Later -> CAD Data managers (in-house, COTS)

• PDM– Mainframe based– Face of drawing

2009 -- 7

Data Management Systems• PDM & CAD “de-linked”

– Release coordination done procedurally– Limited intelligence– “Connection” made via humans

• Newer programs– PDM system handles CAD/PDM data management– PDM/CAD releases in sync– Downstream integration easier– Still some gaps

• Modification and Follow-on programs– Legacy data, new systems and ideas– How do we get from here to there?

Data Migration and Promotion Strategies• When to Migrate?

– Decision tree (is there a valid business case for data migration/promotion)

– Downstream Function impacts?– Customer requirements– Supply Chain impacts?

• Hybrid Raster• 2D to 3D?

– Follow on contracts may facilitate– Automation?

• Hybrid Assembly Models– CATIA V5 CATProduct with V4/V5 Detail Part model files– Only used on F-35 (Right Now)

• CATIA Dataset Ratings– Level 1 through 5

• Best Modeling Practices (CATIA V4)– Organized by Part Types (NC machined versus Composite

laminate)

2009 -- 13

Data Migration and Promotion Strategies– CATIA V5 Methods

• Similar in intent to V4 Best Modeling Practices• Organized loosely with V5 workbenches• Promotion of common modeling practices

– CATIA Customizations• LM Aero developed code to “enhance” the CATIA

driver’s experience• Established and “locked” down environment settings

(V4 & V5)• Some customizations tailored for data management

activities– CAD System Version Upgrades

• New version introduced while program still viable• Similar strategies still apply – there needs to be a

business case to migrate

2009 -- 14

How do you sell data migration to Management?• Existence of legacy and newer programs may

limit methods to produce similar commodities (including engineering)

• Technology Obsolescence– Hardware and Software support– IT Staff knowledge base– Security risks

• Potential for improved product quality and reduced program cost

• Knowledge base for legacy systems and methods waning

– Recent Engineering Graduates not interested in learning V4 or CCD

2009 -- 15

There are some Risks/Costs• Updated documentation required

– Update Procedures– Update Contracts as applicable

• Training on target systems• Hardware/Software Costs• Data migration issues

– Mitigated with translators, healers and quality checkers

– Some touch labor on destination system may be required

• How long does the legacy system coexist with the new system?

– Batch Migrate versus “As Touched”

2009 -- 16

Summary• Data migration is not a perfect science• Goal is to achieve technology and productivity

gains• Risk and Cost involved• Personnel impacts• Don’t forget to check your contracts!• Coordination with Supply Chain critical
