Morning

I have a Kepware OPC server running as a OPC-DA COM connection I have now set it up as an OPC-UA connection.

I naively thought I would just rename the new connection as the old connection and all would be well.  
It seems that OPC path has some additional characters (ns=2:s=)as a prefix, is there a simple way to globally implement this or is it a manual job?

You can export your SQLTags, do a find/replace to add the prefix, then import them again.

Make sure to do a gateway backup before you go messing around with your tags though. ![:thumb_left:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/e26afb081ddde6df016df6ee49159cf56aaca688.gif ":thumb\_left:")
