When attempting to open a model saved in an older version, one of the following errors occur:
”There were unexpected errors during the file-conversion….”
Or
"19: foreign key constraint failed"
This may indicate that the model is corrupt, or that the file is not actually a WaterGEMS, WaterCAD or HAMMER model.
If the file is a .MDB file, make sure it is not an Access Database file (unrelated to WaterGEMS/WaterCAD/HAMMER) and make sure it is not the intermediate Geodatabase file used with WaterGEMS for ArcMap integration (which is separate from the actual model database). If the file has an extension of .MDB and you have Microsoft Access, you can open the file in Access and examine the tables. If there are only tables corresponding to the element types like "junction", and no tables beginning with "HMI...", then the file is an ArcMap intermediate geodatabase.
If you have determined that the file is indeed a model file, please contact technical support to investigate likely database corruption: Forum | Service Request. Reference # 771218.
