CREATE TABLE Failed. 3933: The Maximum Possible Row Length in the Table is too Large. - response (5) by dnoeth

The CREATE was output of a SHOW TABLE, which automatically adds character set info.
If you don't specify it there's a default:
- for CHARACTER SET based on the default for the submitting user
- for CASESPECIFIC based on the session mode: CASESPECIFIC for ANSI and NOT CASESPECIFIC for Teradata sessions
 
Regarding VSAM, it's probably exporting the data and importing it using Teradata's load utilities like TPT.
