Applies to:
Siebel CRM Call Center - Version 17.0 [IP2017] to 18.7 [Release V17]Information in this document applies to any platform.

ACTUAL BEHAVIOR
---------------
Migration Plan has been created and submitted for execution, but the execution was taking long time when executing Schema Service import.
By reviewing the ddlimport*.log file located under filesystem/migration/archive_id/log directory on the target environment it was found that every table was getting all columns being modified.
Below is a snippet of the ddlimport*.log file:

After reviewing the database columns that got modified it was noticed the column definitions were changed to Unicode, example: VARCHAR to NVARCHAR.
EXPECTED BEHAVIOR
-----------------------
The migration application should not change the column definition to Unicode if the database is not Unicode.
STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Have two Siebel IP2017 environments ready for Migration Plan execution using SQL Server database non-Unicode Siebel schema
2. Login to Migration Application
3. Define Source and Target systems
4. Create a Migration Plan
5. Execute the Migration Plan
