Copying Rally project data from one workspace to another via API

I want to copy all the Rally data (user stories, tasks, defects) from one workspace to other workspace under the same subscription.

Basically the requirement is -

Workspace A               Workspace B 
A1                        X1 
B1                        Y1 
C1                        Z1

I want to achieve something like this -

Workspace A               Workspace B 
A1                        X1 
B1                        Y1 
C1                        Z1
                          A1
                          B1
                          C1

I am looking for a solution in Ruby OR Python API which can probably do deepcopy method so that I can retain all the history.

There are solution like deepcopy app in copy - Want to copy Rally stories from one project to another but that did not help us as we want to copy the data from another workspace.

Solution

It can be achieved via Python Rally APIs

import sys
from pyral import Rally, rallyWorkset
options = [arg for arg in sys.argv[1:] if arg.startswith('--')]
args    = [arg for arg in sys.argv[1:] if arg not in options]
server = "rally1.rallydev.com"
apikey = "<Your API Key>"
workspace = "<Source workspace>"
project = "<Source Project>"
rally = Rally(server,apikey=apikey, workspace=workspace, project=project)
rally.enableLogging('mypyral.log')

# Fetch the data for source user story
response = rally.get('UserStory', fetch=True, query='FormattedID = US1234')
for rec in response:

# Switch to target workspace
rally.setWorkspace("<Target workspace Name>")
rally.setProject("<Target Project Name>")
print(rec.oid, rec.Name, rec.Attachments)
rec = { "ObjectID": rec.oid, "Name": rec.Name, "Attachments": rec.Attachments }
try:
    userstory = rally.create('UserStory', rec)
except (RallyRESTException, ex):
    sys.stderr.write('ERROR: %s \n' % details)
    sys.exit(1)
print("UserStory created, ObjectID: %s  FormattedID: %s" % (userstory.oid, userstory.FormattedID))

You can add all the required fields you want to copy to target workspace.

rec = { "ObjectID": rec.oid, "Name": rec.Name, "Attachments": rec.Attachments }
