I just need to know how to migrate process instances that are in a completed state previous snapshot to a new snapshot since we are encountering some problems when we create the reports with exposed variables. These exposed variables only show process instances that are in the current snapshot and it doesn't display the previous snapshot's process instances, because those are not migrated to new snapshot.

Hi Harsha,

Officially, only Active, Failed and Suspended instances can be migrated, Completed instances cannot be migrated. 
But there is a crude way (I have done it once) - you need to change the Completed status as Suspended to make those eligible for migration.
Through APIs, you cannot change the status of an instance, so you need to directly change in the database and the sample SQL would look like - 

update LSW_BPD_INSTANCE set EXECUTION_STATUS = 6 where BPD_INSTANCE_ID = ?

Once the migration is done, set the status back to 2 (Completed).

Please note: This approach is definitely not recommended and if anything is broken, IBM won't provide support, do try it at your own risk and do not forget to take an offline DB backup before doing this experiment.

Thanks!

1.    retrieve the data From REST API

https://IPhost:port/rest/bpm/wle/v1/process/"+tw.local.sourceInstance_Id+"?parts=data

To get process instance variables.

https://IPhost:port/rest/bpm/wle/v1/process/"+tw.local.targetInstanceId+"/variables

To update all process instance  variables needed by source instance id to target instance Id.
