Create bcpnbs.py

Batch Copy Paste No Bull S...

This arcpy script wilæ copy many feature classes from one workspace (file geo database) to another. It's important for me that the script works between existing feature classes, i.e. Not try to create new feature classes, but appends the copied features as new features to the existing feature classes.

If you know Batch-Copy-Paste, this is the same, only without messing up the PLTS_Compilation info.

Due to the above requirements it seemed out of the question to use either of:
arcpy.CopyFeatures_management()
arcpy.FeatureClassToGeodatabase_conversion()
arcpy.FeatureClassToFeatureClass_conversion()
arcpy.Copy_management()
even with the 'overwrite output' turned on, as they all aim at creating a new output feature class.

I therefore decided to go row-by-row with a Search-cursor and an Insert-cursor.
The two .gdb already exist, and have identical structure (schema) but the output.gdb holds no features in the feature classes
