Code Migration StrategiesFull – all historical revisions of files and folders are imported along with their relationships (such as branches and labels) and metadata (such as comments).

Pro:All historical data easily accessible in the new tool

Cons:Repository is filled with cruft which limits the effectiveness of the new toolExpensive in time and money with no guarantee of success and data lost

Snapshot – only selected baselines/milestones are imported. Much of the relationship and nearly all the metadata is necessarily and acceptably left behind.

Pros:Only the most useful historical data is presentCost is limited and definable

Con:All historical data is not accessible in the new tool

• Do have a process to manage change and grant exceptions

• Do hold people accountable to their schedules
