+### How to convert an existing COW table to MOR? 
+
+All you need to do is to edit the table type property in hoodie.properties (located at hudi_table_path/.hoodie/hoodie.properties). 
+But manually changing it will result in checksum errors. So, we have to go via hudi-cli. 
+
+1. Copy existing hoodie.properties to a new location. 
+2. Edit table type to MERGE_ON_READ

Review comment:
       What exactly is the  checksum errors here ?
