We are looking to update tag hierarchies in bulk(product tags). This would be a yearly process to update around ~2300 tags. We have a input csv file with source and target tag hierarchy specified. This should also update the assets with the latest tag hierarchy in AEM. Moving a tag would take care of updating the assets, but this might not be a feasible option for us, given the huge number of tag hierarchy changes.
Any recommendation/best practice to update tag hierarchies and these changes to reflect in associated assets?
