Hi

We are migrating from activiti 5.15 to flowable 6.5 - and I see a serious issue given org.activiti.engine.impl.persistence.entity.ExecutionEntity#getEngineServices property has been removed. This was a convenience method used in activiti 5, and our legacy process definitions does use it to fetch flowable core services runtime/identity.

public EngineServices getEngineServices() {  
return Context.getProcessEngineConfiguration();  
}

We are running our legacy process on a V5 engine as instructed in migration guide but I doubt this is good enough because I don’t see any reference to getEngineServices() at all in ExecutionEntity class and I am not sure how to get around this.

Please advise - thanks!

@joram @martin.grofcik  
Basically all these reference in legacy processes are within scripttask -

ex.  
def identityService = execution.engineServices.identityService;

Not sure if DynamicBPMNServices can be used to correct this on fly?

Hey @binishprab,

In the script you have access to the beans of the engine configuration. So if you are using Spring you can access the services by using `identityServiceBean`.

Yes you can use the `DynamicBPMNService#changeScriptTaskScript` to change the script task of a service.

You have some other options though:

- Change the scripts in all your models and then deploy them again. Use the `SetProcessDefinitionVersionCmd` to migrate your process instances to the new version
- Add your own `ScriptTaskParseHandler` and register it as a `preBpmnParseHandler`.

e.g. Your custom parse handler

```auto
public class CustomScriptTaskParseHandler extends AbstractActivityBpmnParseHandler<ScriptTask> {

    @Override
    public Class<? extends BaseElement> getHandledType() {
        return ScriptTask.class;
    }

    @Override
    protected void executeParse(BpmnParse bpmnParse, ScriptTask scriptTask) {

        String script = scriptTask.getScript();
        if (script != null) {
            scriptTask.setScript(script.replaceAll("execution\\.engineServices\\.identityService", "identityServiceBean"));
        }

    }

}

```

With the last option, you will be changing the script before the activity is created, during the conversion of the XML into the Java Model

Thanks @filiphr - this is great help! Last option to parse and change on the fly works great!

Also, have a look at the section in the migration guide wrt to removal of getEngineServices(): [https://flowable.com/open-source/docs/migration/#engineservices-removed](https://flowable.com/open-source/docs/migration/#engineservices-removed)

@filiphr - if we have multiple different script values to replace, one option is to use regex but that might get ugly soon, any other alternative to substitute multiple different strings…?

Hi @filiphr @joram - even regex won’t be good enough here…suppose you have multiple different scripts to replace, only way I can think of is looking for scriptid and doing a replace but that would be very specific, and won’t handle dynamic replacement for all the scripts - any better ideas?

Hey @binishprab,

You can do multiple `replaceAll`.

e.g.

```auto
scriptTask.setScript(
    script.replaceAll("execution\\.engineServices\\.identityService", "identityServiceBean")
                .replaceAll("execution\\.engineService\\.runtimeService", "runtimeServiceBean")
);

```
