Environment

AEM 6.x

Steps

The instructions below must be run on Mac OS, Linux, or Windows (on Cygwin) with cURL, Python and Java SDK installed:

Go to http://src-aem-host:port/crx/packmgr/index.jsp and log in as admin.
Create a package named "ACL-migration"
Click the Edit button.
Select the Advanced tab and set AC Handling mode to Merge.
Save.
Build the package and download it.
On the file system run this command on the package to extract the META-INF/vault/filter.xml file:

jar -xvf ACL-migration-1.0.zip META-INF/vault/filter.xml
In the same directory, run this command to download a json file of the ACL paths from the source instance. Set the username and password and correct host and replace the xpath query /jcr:root/content//element(*,rep:ACL) with your own):

curl -u admin:admin 'http://aemhost/crx/de/query.jsp?' -G --data '_dc=1507011481908&_charset_=utf-8&type=xpath&stmt=/jcr:root/content//element(*,rep:ACL)&showResults=true' > data.json
Create a file generate-package-filter.py and paste the python code below inside it:

Run the python script from the same folder where data.json was created and save the output to META-INF/vault/filter.xml (replacing the existing contents of filter.xml):

python generate-packge-filter.py > META-INF/vault/filter.xml

import json
from pprint import pprint

with open('data.json') as data_file:
    data = json.load(data_file)

print("<?xml version=\"1.0\" encoding=\"UTF-8\"?>")
print("<workspaceFilter version=\"1.0\">")
for item in data["results"]:
    print("<filter root=\"{}\"/>".format(item["path"]))
print("</workspaceFilter>")

Use this command to update the filter.xml within the zip file:

jar -uvf ACL-migration-1.0.zip META-INF/vault/filter.xml
Upload the zip file to the source instance package manager: http://src-aem-host:port/crx/packmgr/index.jsp
Click Build or Rebuild to build the package.
Download the package from the source AEM server.
Upload the package to the destination AEM server's package manager: http://dst-aem-host:port/crx/packmgr/index.jsp
Click Install to install it.
