Just saw this new exchange project from ignition email.
but there's not much information on how to use it.
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.
