+===== What are the affected CloudBacko Pro versions? =====
+  * CloudBacko Pro v1.x
+  * CloudBacko Pro v2.x
+  * CloudBacko Pro v3.x
+  * CloudBacko Pro v4.x
+===== What action do I need to take to? =====
+  * If your clients are currently on pre MS Exchange 2013 Cumulative Update 20 and do not plan to apply any more updates then you do not need to take any further action.
+  * If your clients plan to continue to backup MS Exchange 2013 and apply the latest MS Exchange updates, then it is recommended to perform a transition from MAPI to EWS backup mode which is based in the Exchange Web Services protocol.
+===== What are the advantages of using EWS backup mode? =====
+  * Improved backup performance & reliability over MAPI.
+  * Flexible deployment – CloudBacko Pro can either be installed directly on the MS Exchange server or on a remote Windows machine for MS Exchange 2013 mail level backups and restores.
+===== What does a MAPI to EWS mode transition involve? =====
+As backup sets using MAPI backup mode cannot be directly converted to EWS backup mode. A new backup set using EWS backup mode must be created.
+The transition will result in the following outcome:
+  * All mailbox items will be re-uploaded again from scratch.
+  * All historical snapshots and retention mailbox items from your previous MAPI backup set will no longer be available for restore from the EWS backup set.
+The transition from MAPI to EWS backup mode will involve:
+  * An upgrade of your CloudBacko Pro to  4.3.x or above.
+  * Creating a new MS Exchange mail level backup set using EWS backup mode.
+  * Running a full backup job to re-upload the Exchange mailbox items again from scratch.
+<WRAP info>
+  * It is recommended to either disable the backup schedule of the existing MAPI backup set or disable the “Run Retention Policy after backup” setting of the existing MAPI backup set
+  * Will require additional storage quota for the affected client. As both the MAPI and EWS backup sets will temporarily co-exist until the transition is complete. After which the MAPI backup set can be deleted, if required.
