Comparing, Adding, and Updating date field in an entity

Trying to compare an existing date from an entity with current date. If entity field (testfield) of entity (testentity) date is equal to OR after current date, then add 1 year to the date in the field.

Issue - For some reason, its reading all the dates and comparing as well but not updating it in the field. I have used post operation step on the entity.

Update: I added ServiceContext.UpdateObject(entity) and ServiceContext.SaveChanges(); to the code but now its giving me "The context is not currently tracking..." error.

Any help would be deeply appreciated. Thanks!

Please take a look at following code.

   public class PostUpdate: Plugin
{

    public PostUpdate()
        : base(typeof(PostUpdate))
    {
        base.RegisteredEvents.Add(new Tuple<int, string, string, Action<LocalPluginContext>>(40, "Update", "new_testentity", new Action<LocalPluginContext>(ExecutePostUpdate)));

      protected void ExecutePostupdate(LocalPluginContext localContext)
    {
        // get the plugin context 
        IPluginExecutionContext context = localContext.PluginExecutionContext;

        //Get the IOrganizationService
        IOrganizationService service = localContext.OrganizationService;

        //create the service context
        var ServiceContext = new OrganizationServiceContext(service);
        ITracingService tracingService = localContext.TracingService;

        // The InputParameters collection contains all the data passed in the message request.
        if (context.InputParameters.Contains("Target") &&
        context.InputParameters["Target"] is Entity)
        {
            // Obtain the target entity from the input parmameters.
            Entity entity = (Entity)context.InputParameters["Target"];


            // Verify that the target entity represents an account.
            // If not, this plug-in was not registered correctly.
            if (entity.LogicalName != "new_testentity")
                return;

                    try
                    {
                        var k = entity["new_testfield"];
                        DateTime m = Convert.ToDateTime(k);

                        DateTime d = DateTime.Now;

                        int result = DateTime.Compare(m, d);

                        // compare the dates 
                        if (result <= 0)
                        {
                            try
                            {


                                entity["new_testfield"] = DateTime.Now.AddYears(1);
                                ServiceContext.UpdateObject(entity);
                            }
                        ServiceContext.SaveChanges();
                  //Adding this is giving me "The context is not currently tracking                    the 'new_testentity' entity."

                            }
                            catch (FaultException<OrganizationServiceFault> ex)
                            {
                            }
                        }
                    }

                    //<snippetFollowupPlugin3>
                    catch (FaultException<OrganizationServiceFault> ex)
                    {
                        throw new InvalidPluginExecutionException("An error occurred in the FollupupPlugin plug-in.", ex);
                    }
                    //</snippetFollowupPlugin3>

                    catch (Exception ex)
                    {
                        tracingService.Trace("FollowupPlugin: {0}", ex.ToString());
                        throw;
                    }
            }
        }

You should register your plugin on the pre-operation step then simply add/change the appropriate value in the InputParameter PropertyBag. That way your changes are inline with the transaction and you don't need a separate update call.

Try attaching your entity to the serviceContext.
