![Ignition Replace Error on UDT](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/9/393f2261d27965dbeef1815505910f39552d1ac5.png)

Search result ‘[default]_types_/Old/E\_Nickel/UDT\_MS/FLT/NON\_CRIT\_STATUS.opcItemPath’ is not a String

Good day,

I am receiving this error after I try to replace the OPC Path Device Name on my UDT tags.

We changed our device name after we started a project which in turn made all of our tags in the designer no longer work because of the path change. Essentially I thought I could just find replace in the OPC path name but it is not looking like I can do this.

Aside from recreating all of my UDTs, is there an easier way to “replace” the OPC path name? For Example:

Instead of : ns=1;s=[**Old**]Program:{StationName}.RECIRC\_PUMP.CATALOG\_NUM

I want: ns=1;s=[**New**]Program:{StationName}.RECIRC\_PUMP.CATALOG\_NUM

Thanks!

This is likely a more complicated bug on our side, but in the short term to fix you could probably just export your tags to JSON, find & replace in a text editor, then re-import over the top of your tags.
