+Upgrade
+=======
+
+**Cps data-updated-event schema v2**
+
+Cps data-updated-event schema v2 used in Jakarta is backward compatible with data-updated-event schema v1 used in Istanbul.
+
+It means that consumers using the schema v2 can process events generated by producers using the schema v2 or v1.
+
+This implies that cps temporal (consumer) must be upgraded from Istanbul to Jakarta at the same time or before cps core (producer) is upgraded from Istanbul to Jakarta.
