Managed Package Class version error

Question

I'm trying to update a Class' API version within a managed package.

The function is as follows:

@HttpPut
global static String uploadNewAttachment(RestRequest req) {

When I try to bump the Class version from 23.0 (old I know) up to anything above 30, I get the error: HttpPut methods do not support parameter type of System.RestRequest at line 5 column 26

But if I clear out the param and use RestRequest/RestResponse instead, I receive: Error: Compile Error: Global/WebService identifiers cannot be removed from managed application: Method String uploadNewAttachment(System.RestRequest) at line -1 column -1

Is there any way around this?

You should be able to remove the @HttpPut annotation, and replace it with @deprecated instead, and then use the new version:

@deprecated
global static String uploadNewAttachment(RestRequest req) {
  return 'Not supported';
}
@HttpPut
global static String uploadNewAttachment() {
  RestRequest req = RestContext.request;
  // Rest of original code here

This should allow you to upload the new version without any problems, and (eventually) you should be able to remove @deprecated methods. This annotation will also prevent future subscribers from accidentally calling the new method.
