Migrating Trac 0.12 from Debian wheezy to Trac 1.0.2 on jessie including all plugins - trac

Question

I try to migrate a trac installation from a debian wheezy server to another debian jessie.
If I copy all files to the new server I get the message, that I have to upgrade with trac-admin /var/trac/blimus upgrade, which seems to work, but it seems not to update all plugins.
for example I had a plugin installed in the old trac, that lets you login on a webpage instead of the htaccess popup.
On the new server I now get the error
Error: Not Found
No handler matched request to /login
How do I get the web-login back?
Is there a way to analyze the old trac folder, which plugins were installed, so I can install the missing ones in the new installation?
I checked the new trac.ini file and added the missing options, this is my trac.ini
These are my versions:
# trac-admin --version
Warning: Detected setuptools version 5.5.1.
Welcome to trac-admin 1.0.2

Answer 1

If the plugin were installed in the Environment plugins directory as eggs, they will be carried over to your new server when you copied the the environment. However, you almost certainly need to upgrade to newer versions, so I suggest deleting the eggs from the Environment plugins directory. The plugins might also have been installed in Python's site-packages. Or they could have been installed using Debian's package manager, I'm not sure if plugins are available there, you might want to search using apt. See Trac Plugin documentation.
Which version of Trac are you running now? I assume it's 1.2.3.
You trac.ini shows that you have 3 plugins installed, and you no longer need one of them in Trac 1.2 (NeverNotifyUpdaterPlugin). You should install these two:
* AccountManagerPlugin
* XmlRpcPlugin
I don't know if Debian packages those for distribution. If not, you can install them with pip.

This instruction will work on Debian jessie (Trac 1.0.2), as well as Ubuntu 14.04 trusty (Trac 1.0.1)

Installation on the new server
