Hi

We are performing a data migration using data pump

The source database is 11.2.0.4

The target database is 12.2.0.1

The source NLS_CHARACTER_SET is  WE8MSWIN1252

The target NLS_CHARACTER_SET is AL32UTF8

During the Import for a few tables we are getting this error

. imported "RDBPARTYCONTACT"                 8.543 MB   96368 rows

ORA-02374: conversion error loading table "CODLTXRP"

ORA-12899: value too large for column DADR1 (actual: 51, maximum: 50)

ORA-02372: data for row: DADR1 : 0X'494E4455535452494553204C414C4942455254C92020202020'

Would it be possible to

1. change the Target Database (12c) CHARACTERSET to WE8MSWIN1252

2. Perform the Import

3. change the Target Database (12c) CHARACTERSET to AL32UTF8

Howdy, Stranger!
