"Can't Change Document's UNID" or "Error Opening Note..." Running "Load Convert" on Database Using Single Copy Template

When running the "Load Convert" utility on a database using Single Copy Template (SCT), you receive the following error:

"Design Replacement Error: Can't change document's UNID"

or

"Design Replacement Error: Error opening note unable to resolve the referenced note"

Opening the database in the Designer client revealed that not all design elements were replaced as indicated by their datestamp.

This issue was reported to Quality Engineering as SPR# MROE5P3L9M and has been addressed in Notes 6.0.3 and 6.5.

Excerpt from the Lotus Notes and Domino Release 6.0.3 MR fix list (available at http://www.ibm.com/developerworks/lotus):

Design
• SPR# MROE5P3L9M - Fix to a code path that errored out replacing a design with one from an single copy template.

There was no problem registering a new user with a template designated as a Single Copy Template or converting an existing Domino 6 mail design (StdR6Mail in this case) to a Single Copy Template.

Supporting Information:
A similar issue occurs when the source template used in the convert process is also using SCT. For more information, refer to the document titled "The Convert Task Is Not Replacing the Design Elements when Single Copy Template (SCT) Is Enabled in Template" (#1112876).

For cases in which similar errors appear when accessing design elements, refer to the document titled "Accessing Design Element in Database Based on SCT Returns: "Error Opening Note Unable to Resolve the Reference Note" (#1165488).
