Data Migration is Like Changing an Engine in Midair …

Product information is the lifeblood of a company

Migration must be done in a way that doesn’t disrupt current process

Improper migrations can be catastrophic

… Garbage In, Garbage Out …

Just because you can migrate all your data doesn’t mean you should

Take a hard look at legacy data and be selective

Do not pollute your new system with corrupt or inaccurate data

… Two Gallons of Water, One Gallon Container …

Critical for companies who are downsizing to a less complex system

Identify critical information early

Verify the target system has structure to accept certain data types

What a Tangled Web We Weave

Map out data sources early

Identify issues like naming conflicts and data integrity

If possible consolidate prior to migration

Volume, Volume, Volume

Assess the amount of data you need to move and factor this into planning

Try reducing the amount of data through purging, deleting and limiting history

Use a phased migration approach to allow for testing and to minimize system downtime

History is Best Forgotten

Extracting and transferring history to a new PLM is challenging

Most companies rarely access earlier versions of data

Using a “Latest only” approach dramatically reduces cost and complexity of data migration

Be Prepared

Don’t “under provision” hardware for data migration

Identify needs and have analysis and data cleansing solutions ready

Clean up your data as much as possible prior to migration

Test, Validate, Rinse, Repeat

Two test passes and a production pass are minimum recommendations for most migrations

Have a specific test plan to evaluate data in the test system

If required to validate combine it with testing to reduce test cycles

Conclusion Good migration is mostly common sense

Don’t let migration be an afterthought

The information is more important than the tool/method of migration
