I am working on upgradation project from Interwoven TeamSite 6.7.2.0 to Interwoven TeamSite 7.3.2.0. So we have to use the same name as previously used. We copied all the files and folder from old workarea, now we are trying to submit the files its giving some "fail to instantiate a workflow model" error. Please suggest me any alternatives to add "&" symbol. Also find the attached screenshot of error message.
