X-Author Migration Manager allows you to perform numerous functions, including migration of templates from one Salesforce org to another. When you migrate non-versioned templates, all template records are essentially copied to the new org with no changes.

With Template Versioning, migration of agreement and clause templates to a new org resets version numbers. All migrated templates are reset to version 1.0 when transported. In addition, if a template has been migrated to another org, and is migrated again into the same org, the newer version will replace any versions that are present.

To understand this more easily, it is important to remember that a template's active version is always copied to the Template record's header details. So, during any migration, the active version of any templates migrated becomes the new version 1.0, regardless of how many versions of that template may exist as nested clause templates. Therefore, any templates that remain unpublished and contained older versions of clauses will still contain those clauses, but there will only be version information in the template record for the active version of the clause template.
