Package: collective.migrator
Introductioncollective.migrator is a buildout based tool to help migrate content between Plone/Zope instances.
It can be installed as follows:$ easy_install collective.migratorOnce installed you can run the tool to set up the migration environment$ migratorThis creates a folder calledmigratorand installs a buildout environment there. All further actions are run from this folder.The first thing that you want to do at this point is customize theinstance.cfgfile.By default it looks like this:[remote]
host = xxx.webfactional.com
user = ssh_user
port = 8080
extensions = /usr/Plone-2.5.5/zeocluster/client1/Extensions
zmi_user = admin
zmi_pwd = admin
root = Plone
export = /usr/Plone-2.5.5/zeocluster/client1/var

[local]
host = localhost
port = 8080
extensions = /home/suresh/plone4/parts/instance/Extensions
zmi_user = admin
zmi_pwd = admin
root = Plone
import = /home/suresh/plone4/var/instance/importThis defines the settings for all the Plone instances involved in the migration.Thebuildout.cfgdefines the steps that will be executed as part of the migration.Here is the default content:[buildout]
extends = instance.cfg
    migrate_frontpage.cfg
    migrate_users.cfg
    migrate_props.cfg
parts =
tbd =
    ${migrate_frontpage:parts}
    ${migrate_users:parts}
    ${migrate_props:parts}As you can see,partshas been intentionally left blank. Alsoinstance.cfgdescribed previously is being used here. The othermigrate_.cfg* files contain some sample steps to move various objects between the instances.As a simple test, you can changepartsinbuildout.cfgto look like this:parts = export_frontpageThis step is defined inmigrate_frontpage.cfg.Now after you run buildout as follows:$ bin/buildoutyou should notice that the front-page object has been exported in the remote Plone instance. Once you gain more confidence in the tool, you can even try to run the other steps found in themigrate_.cfg* files.PS: This may not be the “coolest” way to manipulate your Plone and some of these actions may be better done with GenericSetup profiles, but this worked for me!TroubleshootingA couple of people have reported the following error:# migrator
INFO: Starting migraton.
Traceback (most recent call last):
  File "/opt/python/bin/migrator", line 5, in ?
    from pkg_resources import load_entry_point
ImportError: No module named pkg_resourcesNot sure what causes this, but I suspect a flawed python installation.virtualenvis a good tool
to protect against this situation. The following modified installation procedure can be used in this
case:$ easy_install virtualenv
$ virtualenv --no-site-packages <my-folder>
$ . <my-folder>/bin/activate
$ easy_install -U setuptools
$ easy_install -U zc.buildout
$ easy_install collective.migrator
