This module provides a plugin which dedupe taxonomy terms merging them into one during a migration.
If you have duplicated terms in a vocabulary you are about to migrate, this plugin will only migrate the first occurrence of a term, skip the other rows with the same name but it will map the migrated term id with every source id which has the same name (so if you have other content tagged with these skipped terms id, those content will be attached to the term id that has been migrated when you will use the migration_lookup).
If you want to merge different terms name into one during your migration, you just need to rename those terms in your source (database, csv, json, etc.) so that they have the same name, then use this plugin during the migration and that's all.
