DB2 Enterprise stage Complicated setup with cross server mount Replaced with DB2 Connector Stage using tool Easy setup More modern and flexible interface More options
Connector Migration Tool
POC August 2012 Estimate time consumption Rewrites Migrated to Quite painful, meny rewrites
Windows Client does not support Windows 7 Skip poc, do the migration! Keep virtual XP clients until end of project

Production environment Installed in December 2012 XlC 12 not supported, changed to XlC Gb RAM compared to 30 Gb for 8.1
Performance tests January 2013 Find optimal numer of concurrent jobs Tried 1-60 concurrent No more than 10.
