Errors after migrating a trac project

[Freddd]

I am having the following errors after migrating a trac project to a different server.

1. When I first log in I get this:

   'Trac detected an internal error:
   OperationalError: no such table: tags'
   

2. When I click on the tags or Dashboard link on the top of the page I get

   Trac Error
   An error occurred while loading Backlog data: no such column: b_strict
   

3. The product backlog link and view sprint links aren’t showing in the left pane.

I migrated from server A to server B.

In server A:

Trac: 	0.11
Python: 	2.5.2 (r252:60911, Oct 5 2008, 19:49:54) [GCC 4.3.2]
setuptools: 	0.6c9
SQLite: 	3.5.9
pysqlite: 	2.4.1
Genshi: 	0.5.1
mod_python: 	3.3.1
Agilo: 	0.9.4
Pygments: 	0.10
Subversion: 	1.5.1 (r32289)
jQuery:	1.2.3

In server B:

Trac: 	0.11.3
Python: 	2.4.6 (#2, Jan 24 2010, 12:20:41) [GCC 4.3.2]
setuptools: 	0.6c9
SQLite: 	3.5.9
pysqlite: 	2.4.1
Genshi: 	0.5.1
Subversion: 	1.5.1 (r32289)
jQuery:	1.2.6

I followed this steps:

Migrate SVN and TRAC

1. $ svnadmin dump /path/to/repo > reponame.dump
2. $ svnadmin create /path/to/new/repo
3. $ svnadmin load /path/to/new/repo < reponame.dump
4. $ sudo trac-admin /var/www/newproject/agilo_trac/ resync

I would appreciate any suggestions/help. Please let me know if I submitted this in the wrong place.

Thank you.
