Renaming all feature classes in file geodatabase?

Question

I have 8 separate geodatabases in which are contained tiled feature classes all of the same name e.g. TopographicArea. So that each of my File Geodatabases contain a feature class called TopgraphicArea etc..

I would like to be able to merge the feature classes from each geodatabase of the same type (e.g all feature classes called TopgraphicArea etc..) but as it stands I can't because the names are identical.

How can I rename, or append a suffix to, each feature class so that they can subsequently be merged?

Ideally I'd like the feature classes in gdb1 to be "1" in gdb2 to be "2" and so on and preferably to be done in ModelBuilder.

This code is pretty simple, but it should work for what you want to do. Again, in the time it took to write the code, you could rename the featureclasses by yourself, but the logic works if you need to scale it up to a larger number.

import arcpy
from arcpy import env

# Set Output Geodatabase Name
outgdb = "C:/workspace/outfc.gdb"

#Set Range to cycle Through
for num in range(1,8):
  #Set workspace to gdb name and iterator number
  env.workspace = "C:/workspace/gdb" + num + ".gdb"
  #List featureclasses in that workspace
  fclist = arcpy.ListFeatureClasses()
  #Iterate through featureclasses
  for fc in fclist:
    oldnm = fc
    #Rename featureclasses to old name plus iterator
    newnm = fc + num
    arcpy.Rename_management(oldnm, newnm, "FeatureClass")
    #Copy renamed featureclasses into Output Geodatabase
    newloc = outgdb + os.sep + newnm
    arcpy.Copy_management(newnm, newloc, "")
