Can not find the target method after changing namespace


I have some jobs in Retries tab, that have the following status [Can not find the target method.] after updating the namespace of the job.

The way I am registering the jobs is as following:

private readonly IBackgroundJobClient _backgroundJobClient;

_backgroundJobClient.Create(Job.FromExpression(step => step.Run(data)), new EnqueuedState(_backgroundEngineSettings.ProcessingQueue));

Is there a way to ignore the assembly when hangfire is trying to resolve the job ?
Or does hangfire provide a method for updating existing data through a sql migration script or some sort ?

Thank you!
