Hi,
Need a suggestion or guidance regarding process instance migration from the earlier version of BPMN to latest.
Is it possible to add/update local variable of specific activity or somehow update process instance. We are migrating process instance from older to new version through java implementation but in our latest version we have few new input/output variables (defined in BPMN) and timer boundary event as well and we define timer definition through this newly introduced variables and while migrating to new version from older one(timer boundary event in new version) it is throwing null pointer exception while migrating.
Ref:
The activity “Evaluate Work” has been introduced with boundary timer event in latest version. with new filed in local variable step as “sla”.
On migrating the 1st version of process instance we are facing issue while introducing “sla” variable field in “step” for latest version
