Why do we have Clearcase SCM integration and also PTC's own product -Integrity SCM Solution (MKS product) within wind-chill???
It is not clear to me why do we have clearcase integration (which is a competitor product to MKS) and also MKS integrity SCM tool (Now PTC product) in same wind chill platform.
Does this mean that Winchill user can still make independent decision of which SCM software to use or it was the just product evolution phase where wind chill integrated Clearcase first and later bought MKS integrity.
Does in any way having clearcase integration within wind chill will able to migrate database of clearcase to MKS integrity SCM smoothly or still we have same set of challenges like another data migration.
