The Migrate request failed because another Migrate for this change package using the same Migration Scheme is already active.
Explanation
Since migration can potentially affect a large
number of Resource Definitions, they are
serialized by Migration Scheme and Change Package
name. In this case, another migration request
for the same Change Package and Migration Scheme
was already active.
System action
The CICSĀ® Configuration Manager batch command interface run is
terminated.
User response
Resubmit the job when no other Migrates using the
same Migration Scheme and Change Package are
active.
