I have been working on exporting attachments from a point feature class by location (County).  The export is renamed by the area (County), which contains the feature class, attachment table, and the relationship class, using this: 

import arcpy, os, datetime, traceback, sys

Start = datetime.datetime.now()

print ('Running Elevation Certificate by County Export ' + str(datetime.datetime.now()))

#Set Environmental Setting
arcpy.env.maintainAttachments = True

# Select County polygons and export to folder
DOMAIN_COUNTIES_TABLE = r"S:\Projects\CFI_Models\USNG_Demographics_Statewide\Domain_Counties.gdb\DOMAIN_COUNTIES"
DOMAIN_COUNTIES_Descript = "Descript"
DOMAIN_COUNTIES_CURSOR = arcpy.SearchCursor(DOMAIN_COUNTIES_TABLE)
for row in DOMAIN_COUNTIES_CURSOR:
    COUNTIES_DESCRIPT = row.getValue(DOMAIN_COUNTIES_Descript)   

    #Feature Class to Geodatabase
    infc = "T:\Projects\Elevation_Certificates\ECs_Hosted_20200929.gdb\ELEVATION_CERTIFICATES"
    outgdb = "T:\Projects\Elevation_Certificates\ECs_Archive_by_County.gdb"
    where_clause = "\"COUNTY_COMMUNITY\" = '%s' " %COUNTIES_DESCRIPT
    print ("Exporting: " + '%s' %COUNTIES_DESCRIPT)
    StartTime = datetime.datetime.now()
    arcpy.FeatureClassToFeatureClass_conversion(infc, outgdb, "%s" %COUNTIES_DESCRIPT, where_clause)
    EndTime = datetime.datetime.now()
    DeltaTime = EndTime - StartTime
    TimeDiff = str(DeltaTime)
    print ('Process Time: ' + TimeDiff)
                                       
print ('Completed County Feature Class Export ' + str(datetime.datetime.now()))

End = datetime.datetime.now()
Delta = End - Start
Time = str(Delta)
print ('Process Time: ' + Time)

This yields everything I need but loses the relationship.  Any ideas how to rebuild this relationship or how to successfully export the data that carries the relationship class?

Thanks,

Daniel
