Below are the outputs of ein and gi with the uppercase notation.

wbemcli ein http://root:password@localhost/root/virt:Virt_MigrationJob
localhost:5988/root/virt:Virt_MigrationJob.instanceid
="066259d5-4c5a-4b1f-991f-0d839f105a68"

wbemcli gi http://root:password@localhost/root/virt:Virt_MigrationJob.
InstanceID="066259d5-4c5a-4b1f-991f-0d839f105a68"
localhost:5988/root/virt:Virt_MigrationJob.InstanceID
="066259d5-4c5a-4b1f-991f-0d839f105a68"
OtherRecoveryAction,RecoveryAction,ErrorDescription,ErrorCode,DeleteOnCompletion=TRUE,PercentComplete,Priority,Owner,Notify,UntilTime,LocalOrUtcTime,RunStartInterval,RunDayOfWeek,RunDay,RunMonth,JobRunTimes=1,ElapsedTime,StartTime=20080201081420.535009+480,ScheduledStartTime,TimeSubmitted,JobStatus,CommunicationStatus,OperatingStatus,DetailedStatus,PrimaryStatus,HealthState,Status="Running",StatusDescriptions,OperationalStatus,InstallDate,Caption,Description,ElementName,InstanceID="066259d5-4c5a-4b1f-991f-0d839f105a68",Name="Migration",JobState=4,TimeOfLastStateChange,TimeBeforeRemoval=00000000000500.000000:000

Also, the output of gi with the lowercase notation as follows:
wbemcli gi http://root:password@localhost/root/virt:Virt_MigrationJob.
instanceid="066259d5-4c5a-4b1f-991f-0d839f105a68"
localhost:5988/root/virt:Virt_MigrationJob.instanceid
="066259d5-4c5a-4b1f-991f-0d839f105a68"
OtherRecoveryAction,RecoveryAction,ErrorDescription,ErrorCode,DeleteOnCompletion=TRUE,PercentComplete,Priority,Owner,Notify,UntilTime,LocalOrUtcTime,RunStartInterval,RunDayOfWeek,RunDay,RunMonth,JobRunTimes=1,ElapsedTime,StartTime=20080201081420.535009+480,ScheduledStartTime,TimeSubmitted,JobStatus,CommunicationStatus,OperatingStatus,DetailedStatus,PrimaryStatus,HealthState,Status="Running",StatusDescriptions,OperationalStatus,InstallDate,Caption,Description,ElementName,InstanceID="066259d5-4c5a-4b1f-991f-0d839f105a68",Name="Migration",JobState=4,TimeOfLastStateChange,TimeBeforeRemoval=00000000000500.000000:000
