Few days ago we have been asked about the risk factor in migrating in-flight instances in IBM BPM 7.5.1
After few discussion, calls and google search we came to conclusion that in-flight data migration is a good but risky approach as instances might fail during migration. To lower risk we have recommended below steps.
- Regressive testing of instance migration from snapshot A to snapshot B in lower environment.
- If possible make prod like environment by restoring prod DB in lower environment and do instance migration to new snapshot before going live.
- Take backup of LIVE DB before doing data migration.
And most important thing
- Take advice from actual development team if they have removed any variable, task or component where token can be while migration
Also, are they comfortable about their Process Model and Process data structure as described below
- Process Modeling should be “Encapsulate what varies”
- Process Data Structure should be “Open for extension, closed for modification”
