Thanks for your reply Thomas. 1) The DB file was not re-created when upgraded to the higher version from 1.3.160 to 1.3.169. Ideally, It was not noticed that a different higher version of the h2 jar file was getting used in the application than the h2 DB file that was created with the lower version. 2) My concern is all about, if there, such a problem due to the conflict of version, why all DBs have not thrown this exception where as only few? 3) DB URL is: jdbc:h2:<H2_DB_File_Path_with_file_name_excluding_.h2.db>;CIPHER=AES;MVCC=TRUE;AUTO_SERVER=TRUE 4) Yes, Before any update through the application, a H2 DB back-up will be taken.
