Is it a tool that can delete the unused historian tags?

I have not used it so I cannot say for sure.

But off the description I would say no.

It looks like it just copies and paste data from a list of tag paths which no longer exist to their new location.

I have a bunch of zombie tags in the historian database of each project.

There's a way to remove them but it is manual operation to each tag, which takes a long time to remove due to the amount of tags in each project.

Looking forward a solution to remove the tags in a more efficient way.

I'm sure you could write a script to automate this.
