+Upgrade from Istanbul to Jakarta
+================================
 
-**Cps data-updated-event schema v2**
+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.

+Database
+--------
+
+In Jakarta, CPS Temporal database is upgraded from TimescaleDB ``2.1.1`` running PostgresSQL ``13.2`` to
+TimescaleDB ``2.5.1`` running PosgresSQL ``14.1``. This is a major PostgresSQL upgrade subject to change data storage
+format. Then, any existing CPS Temporal data from Istanbul needs to be migrated before it can be used in Jakarta.
+
+The migration needs to be done in 2 main sequential steps for both TimescaleDB and PostgresSQL:
+
+#. Upgrade TimescaleDB from 2.1.1 to 2.5.1
+#. Upgrade PostgresSQL form 13.2 to 14.1
+
+Bellow are the detailed steps to be completed for data migration (manual docker steps, to be reviewed for
+production upgrade).
+
+* Stop CPS Temporal Istanbul service.
+
+* Backup 2.1.1-pg13 data. This backup is to be used to restore data if needed.
