Syncronization of work items after minor chnages to schema

Currently we are at 3.0.1.2 and WAS 7.x. OS is Windows 2008 Server (32-bit).

In the ccm.log I see the below messages with different work item numbers (the below one is for 2393) as and when the work item gets changed (state transition, field changes etc). We changed the schema (some enumerations were not mapped properly). Should we synchronize all the exiting work items for this error message to go off?
