Policy Version Control

Hi, Our organization ISO 9001 & 27001 certified. Tow year before we are implemented the incident management policy, the policy version number is (Ver 1.0). Last year as per the  management direction the information security incident management policy was migrated with QMS policy. Owing the information security incident management policy was obsoleted.   Current financial the QMS incident management policy is not effective, hence the management decided that, the information security incident management bring back to live.   Please guide us, what is the version I can provide the policy. Because the existing one already obsoleted. Now I can provide the version number from the start or I can follow the old version number.   If you suggest follow the old version number or new version number means, provide the valid reason for the same. We can communicate to the management.   Thanks in advance. G Thanikachalam
