Loop through folder of MXD and change server name

[Brian_McLeer]

We are changing our production server to have a prefix of 'HV'. I have a folder of MXDs I would like to update to the new server, but I am missing something from my code below. I got my start from https://gist.github.com/davehorsey/d8892b150e61d2e03617. 

import arcpy, os
path = r"C:\layouts"
for fileName in os.listdir (path): 
 basename, extension = os.path.splitext(fileName)
 
 # select MXD files that do NOT begin with "Copy_of_" - this 
 # prevents the script from updating files that have already been updated
 if (extension == ".mxd") and (fileName[:8] != "Copy_of_"):
 fullPath = os.path.join(path, fileName)
 mxd = arcpy.mapping.MapDocument(fullPath)
 print fullPath
 
 # update data sources
 mxd.findAndReplaceWorkspacePaths("Database Connections\\Server Database NT Auth.sde", "Database Connections\\HV_Server Database NT Auth.sde")
 print "\tUpdated: SDE data sources"
 
 # check for broken links
 brknList = arcpy.mapping.ListBrokenDataSources(mxd)
 for brknItem in brknList:
 print "\tCheck: " + brknItem.name + " data source broken"
 if not brknList:
 print "\tCheck: no broken data sources"
 
 # save a copy of the MXD
 saveACopy_filename = "Copy_of_" + fileName
 saveACopy_fullpath = os.path.join(path, saveACopy_filename)
 mxd.saveACopy(saveACopy_fullpath) 
 print "\tSaved: " + saveACopy_filename
 
 del mxd
 
 # delete the original MXD
 arcpy.Delete_management(fullPath)
 print "\tDeleted: " + fullPath‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi Brian,

I've had success with the following script.  It will iterate through a directory and child directories and update all database connections with the one specified in the newDataSource variable.

import arcpy, os
from arcpy import env
from arcpy import mapping

# Parent directory to MXDs.  Script will iterate through Child directories
env.workspace = r"D:\Temp\Python\MXDs"

# New Enterprise Geodatabase
newDataSource = r"Database Connections\DBO@GIS.sde"

env.overwriteOutput = True

for (path, dirs, files) in os.walk(env.workspace):
    for file in files:
        if ".mxd" in file.lower():
            mxd = os.path.join(path, file)
            print(mxd + " is being processed")
            mxd = mapping.MapDocument(mxd)
            for df in mapping.ListDataFrames(mxd, "*"):
                for lyr in mapping.ListLayers(mxd, "*", df):
                    try:
                        if lyr.supports("DATASOURCE"):
                            if lyr.serviceProperties['Database']:
                                print("\tUpdating " + str(lyr))
                                lyr.replaceDataSource(newDataSource, "SDE_WORKSPACE", "")
                                print("\tSuccessfully updated data source")
                    except AttributeError:
                        pass
            mxd.save()

del mxd‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks, Jake,

That worked for one data source, unfortunately, I have 3 databases referenced in the MXDs. Is there an 'if else' statement to point it towards the next database if the first one does not work?

[Brian_McLeer]

I should say if the first database connection does not contain the layer to reference to, but the layer is in the next database.

I haven't test, but you could try the following:

import arcpy, os
from arcpy import env
from arcpy import mapping

# Parent directory to MXDs.  Script will iterate through Child directories
env.workspace = r"D:\Temp\Python\MXDs"

# New Enterprise Geodatabase
newDataSource1 = r"Database Connections\DBO@GIS.sde"
newDataSource2 = r"Database Connections\USER1@GIS.sde"
newDataSource3 = r"Database Connections\USER2@GIS.sde"

env.overwriteOutput = True

for (path, dirs, files) in os.walk(env.workspace):
    for file in files:
        if ".mxd" in file.lower():
            mxd = os.path.join(path, file)
            print(mxd + " is being processed")
            mxd = mapping.MapDocument(mxd)
            for df in mapping.ListDataFrames(mxd, "*"):
                for lyr in mapping.ListLayers(mxd, "*", df):
                    try:
                        if lyr.supports("DATASOURCE"):
                            if lyr.serviceProperties['Database']:
                                print("\tUpdating " + str(lyr))
                                try:
                                    lyr.replaceDataSource(newDataSource, "SDE_WORKSPACE", "")
                                    print("\tSuccessfully updated data source")
                                except:
                                    try:
                                        lyr.replaceDataSource(newDataSource2, "SDE_WORKSPACE", "")
                                        print("\tSuccessfully updated data source")
                                    except:
                                        try:
                                            lyr.replaceDataSource(newDataSource3, "SDE_WORKSPACE", "")
                                            print("\tSuccessfully updated data source")
                                        except:
                                            print("\tCould not update " + str(lyr))
                                            pass
                    except AttributeError:
                        pass
            mxd.save()

del mxd‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks Jake,

You saved me a bunch of time!
