title: Microsoft Dynamics CRM 4.0 using 3.0 Callouts and Workflows
body: <p>We are migrating to CRM 4.0 from 3.0. In this process, we have had our data migrated from our existing CRM 3.0 instance to a new CRM 4.0 instance.</p>
  
  <p>This has been going all well and good until I got to the point of installing our existing callouts and workflow DLLs.</p>
  
  <p>I know that I need to rewrite them, but our migration schedule does not have time alloted for this.</p>
  
  <p>Can anyone point me towards how to install my CRM 3.0 Callouts and Workflow DLLs so that I see them in CRM 4.0? My Google-Fu for this subject has failed me.</p>
  
  <p>Edit: At this point, I am about resigned to the fact I need to spend the weekend rewriting them as plugins.  If anyone can point me to a good resource that walks through taking a 3.0 callout and converting it into a plug, I'd enjoy that too. Everything I've found on 4.0 plugins assumes you are creating a new one. </p>
