Issue/Introduction

Datacom/DB does not provide the ability to upgrade multiple releases at once, so you must upgrade to each release progressively. 

Being so, when upgrading from 11.0 to 15.1, you have to upgrade from version 11.0 to 12.0 first, then from version 12.0 to 14.0 and finally to version 15.1.

 

Environment

Release:  11.0 12.0 14.0 15.0 15.1 
Component:  Datacom/DB

Before upgrading from Datacom/DB version 11.0 to 12.0:
