I have a versioned ArcSDE annotation feature class in prod SDE database. It is to be updated from an unversioned annotation feature class in the staging SDE database. The staging annotation feature class will be built from scratch each month. The staging and the prod have the same attributes. The production is versioned because it is slightly edited and also archieved in ArcSDE. I can't think of a way to do this update in FME. I can use fme_db_operation and "Write Mode = UPDATE", but there is no common update key fields between the staging annotation class and the production annotation class. I tried using "TEXTSTRING", but it does not seem to work.
