In one of my SDE (SQL Server) polygon feature classes, I have been having too many issues with annotation moving or changing unnecessarily due to edits. Since there are only 30 records, I plan to convert the 4 annotation files (different scales) back to non-feature-linked annotation.
I can't copy the FL layers to a test file geodatabase to test, and I don't have a test SDE to test in. It looks like I'll be able to just delete the relationships between the feature class and the 4 annotation features. Is there anything else I should know before I try this? Quirks? geodatabase annotation
