Failed to execute (UpgradeDataset).
I can't edit the annotation on an ArcGIS Pro 2.3.1 project. It's an imported MXD with an annotation feature class. Using arcpy I attempted to upgrade the anno, but got an error. I haven't contacted ESRI Support yet because I wanted to see if anyone knows about this. There was a similar question regarding upgrading asked, but it was using the tool: https://community.esri.com/message/799004-re-how-do-i-upgrade-annotation-for-use-in-pro?commentID=799004#comment-799004
