I have been given the task of proving whether or not we can upgrade our CRM 4 platform tenant to either CRM 2011 or CRM 2013. However I have read on a Microsoft website the following:
Legacy features that are no longer supported
With the launch of CRM 2013, we are officially dropping support for legacy CRM 4.0 features. These features were deprecated with Microsoft Dynamics CRM 2011 and will no longer work with this new version.
Dynamics CRM 4.0 features that will no longer be supported:
- CRM 4.0 plug-ins
- CRM 4.0 client-side scripting
- CRM 4.0 custom workflow activities
- CRM 4.0 web service API (also known as the 2007 web service endpoints)
- ISV folder support for custom web applications
At present the one tenant (only one active within this CRM 4 platform) has some custom JavaScript code added to some of the entity forms being used in the system.
My question is will upgrading CRM 4 to either CRM 2011 or CRM 2013 cause any of these JavaScript modifications to be removed or break?
Thanks and I appreciate any help with this as could save me a lot of time proving something won't work.
