Importing tags in 7.9 from 8.0

Ignition
1

I am trying to export tags from 8.0.5 in xml file and then import them into 7.9.10.
I am getting a Null Pointer exception

org.xml.sax.SAXException: java.lang.NullPointerException: Path cannot be null.
java.io.IOException: java.lang.NullPointerException: Path cannot be null.

caused by IOException: java.lang.NullPointerException: Path cannot be null.
caused by NullPointerException: Path cannot be null.

Ignition v7.9.10 (b2018112821)
Java: Azul Systems, Inc. 9.0.7.2

As a test, I tried exporting tags from 7.9.10 in 8.0 and then exported the same set of tags back to 7.9.10 and got the same error.

Any ideas on how to import the tags.
I tried using copy-paste too and that didn’t work either.

You can’t go backwards. Not for anything in Ignition. There are a handful of special cases where you can edit an export and get away with it, but most things change too much from version to version.
