merge identical tags

Hello ,
I want to export all the images from one database and import them into another database.
when I export the dataset and import it into the new database I noticed that the tags are kept.
the problem is that tags are created multiple times. indeed if a tag is used for two different images, this tag is created twice. Is there a way to merge identical tags?
thank you very much
