+================
+Upgrade Strategy
+================
+
+OSDF can be upgraded in place(remove and replace) or in a blue-green
+strategy.
+
+There is no need for database migration. Since, there is no database
+being used by OSDF.
+
+Supporting Facts
+================
+
+OSDF is a stateless component. It doesn't store any information in the
+database. It holds on to the optimization request in memory only until
+the optimization process is complete. The optimization is done either by
+OSDF itself or other external components(such as HAS) are leveraged for
+optimization.
