ArcGIS 10.0 – How to Batch Convert ArcGIS 9x Files Using Python

arcgis-10.0importpython

I would like to convert all mxd's in a directory and it's subdirectories to ArcGIS 10 mxd's. This is so that I can then run python to automate some updates within them.

Is this possible?

This is my second post and I was also wondering if I should post sample code?

=== UPDATE — Here's the code (for more usefully) converting 10 files to 9.3

#Downgrades all ver 10 mxds in directory and subdirectories to version 9.3
#and saves them with _93 extension.


import arcpy, glob, os

path = os.getcwd()
for pathname, directories, filenames in os.walk(path):
    for filename in filenames:
        if filename.lower().endswith(".mxd"):
            mxd = arcpy.mapping.MapDocument(os.path.join(pathname, filename))
            filename, ext = os.path.splitext(os.path.join(pathname, filename))
            if mxd.dateSaved:
                    print mxd.dateSaved
                    mxd.saveACopy(filename + "_93" + ext, "9.3")
                    currentMxd = filename + "_93" + ext
                    mapDoc=arcpy.mapping.MapDocument(currentMxd)
                    print "Updated: " + filename
            else:
                    print filename + "is not version 10 therefore not altered"

Previous MXDs should load, no need for conversion. However, it will save to 10.0 when you save your updates.

However:

import arcpy
import glob
import os

for pathname, directories, filenames in os.walk(r"c:\startdir"):
    for filename in filenames:
        if filename.lower().endswith(".mxd"):
            mxd = arcpy.mapping.MapDocument(os.path.join(pathname, filename))
            filename, ext = os.path.splitext(os.path.join(pathname, filename))
            mxd.saveACopy(filename + "_10" + ext)

This will save a duplicate copy of each .mxd as a 10.0 MXD under the name <filename>_10.mxd. Though, again, you don't need this. You could also replace the saveACopy line with .save() and just replace each MXD.
