Hi Volker
Thanks for the suggestion.
I tried your first approach (in source DB) and then did the migration.
This helped me also to get rid of 'right truncation error' while migration.
Now, I am getting another error while 'decrypting the data'.
Database error -851: Select Error: SQLSTATE = 08001 [Sybase][ODBC Driver][SQL Anywhere]Decryption error: Input must be a multiple of 16 bytes in length for AES
Although I still need to go through the details and try of find the root cause but though to share.
Thanks
Ramendra
