7.9 upgrade to version 8 pain points

Anyone have a list of things to watch out for during this process?

Things I have:

  • system.tag.read() / write() deprecated but still usable. failures dont tell you much information in the log, try to use the new versions

  • system.tag.browseTags() reworked to system.tag.browse() . recursive added back in 8.1.2!


  • Tag.LastChange is changed to Tag.Timestamp . still might work the old way? probably best to do a find and replace and use .TimeStamp

  • tag parameters now more easily accessed

This is my list after a couple of upgrades

Nick links to it in his post about this, but do make sure to read through the upgrade guide: 7.9 to 8.1 Upgrade Guide - Ignition User Manual 8.1 - Ignition Documentation
