Migration of Classic Glossary Terms
If the migration tool is used without proper preparation, there may be data loss or corruption of classic glossary terms, templates, and relationships, leading to confusion and inefficiencies in data governance.

Read-Only Status of Classic Terms
Post-migration, classic glossary terms will become read-only, which may hinder users' ability to update or manage these terms effectively, impacting their workflow and data management processes.
