Hi guys, I would like to know if there is safe way to delete an archived timestamp tags in bulk?

You can use PI SQL Commander

PowerShell Tools are a quick/simple way to bulk delete data, especially if you don't have the SQL tools installed.

Note that PowerShell Tools for the PI System requires PowerShell 5.1. This was the last version of PowerShell to support .NET Framework, which is needed because under the covers PowerShell Tools for the PI System uses AF SDK calls, and AF SDK currently has a dependency upon .NET Framework.

If you do not already have PowerShell 5.1 installed, you may have explicitly search for it. PowerShell 6 or above will not work with PowerShell Tools for the PI System.

thank you guys for all of your answers

I have yet to see 6+ installed in any Enterprise environment (in base OS images). Have you seen that anywhere? Just curious.

Can you suggest any documentation? or in customer portal we can see?

Can you advice any documentation?
