Centralized or Distributed Considerations • Enterprise Standard

• How does the team work?

• Developer preference?

• Who is part of the team?

• What processes are in place?

• What types of files are worked on?

Active Code Migration


• Inventory of VOBs, VOB Servers, View Servers, Registry Servers, License Servers

• Inventory of Projects – Map Projects / Programs to VOBs

First build an Inventory

• Benefit Analysis

– Server retirements

– Data Center retirements

– License / Maintenance

– Upgrade costs

• Costs

– New Equipment

– New tooling

– Software Engineering

– clearmake or snapshot?

– Training

• Orphaned Projects

– No one knows what they are for

– Can you map Project to Product?

Portfolio Analysis - CBA


• Management of Change

• Bring all ClearCase Admins into single team

• Restrict all “Shadow Admin”

• Archive all legal records

• Define “Active Code” – that’s what you move

• Lock migrated VOB in read-only for 90-180 days to provide safety net.

Draining the Swamp


• Don’t get in the way of Product delivery

• Don’t allow years of Technical Debt to be added to the migration bill

• Do have a process to manage change and grant exceptions

• Do hold people accountable to their schedules

Draining the Swamp has it’s dangers
