[Zope] How to move acl_users from a Zope 2.7.8 server to Zope 2.10.7 ?

[Aleksey Tsalolikhin]

Hi.  I am moving a Web application from a Zope 2.7.8 server to 2.10.7.

How do I migrate the users in acl_users from the Zope 2.7.8 server to
the 2.10.7 one?

Andreas Jung suggested exporting it from the old server and importing
in the new.

Apparently this worked (although I had to blow away the "acl_users"
folder on the
new server before I could import the "acl_users" folder from the old server; and
I had to use zpasswd.py to create "inituser" and "access" files in my Zope root
so that I could access the ZMI to import the acl_users folder.)

I have very little experience with Zope so I turn to you guys, is this
a totally insane
thing I did, or is it absolutely correct and I (and Andreas) should be
rewarded?  :)

I did try using the copy_users.py script but had no luck with it.  :(

The record of my attempt follows.

If somebody has experience with migrating acl_users from one server to
another, please write me!

I put the copy_users.py file in /var/lib/zope/Extensions and added it
as an External Method

(fill out the form as copy_users, copy_users, copy_users and copyUsers)

then add a DTML Method as per the instructions

-------------------------------------------------------------------------------


I created a DTML Method called do_copyUsers:

<dtml-call "copy_users('acl_users', 'copy_of_acl_users')">


but when I ran it, I got:


Site Error

An error was encountered while publishing this resource.

Error Type: KeyError
Error Value: 'copy_of_acl_users'

so I created an empty folder called copy_of_acl_users

and tried running my DTML method again ,but got:
ite Error

I also tried removing /copy_of_acl_users and recreating it again, but this
time I checked the "create user folder" box.

Tried running my DTML method again, but again got

Error Type: AttributeError
Error Value: _addUser

I also created a copy of the acl_users folder in /aleksey_temp/acl_users


Modified my DTML method to:

<dtml-call "copy_users('acl_users', 'aleksey_temp/acl_users')">

and when I ran it, Zope output a zero byte file called do_CopyUsers


Best,
