[Mageia-sysadm] Tx upgrade

[Michael Scherer]

Hi,

as asked by i18n team since some weeks, I propose we upgrade transifex
on alamut to the latest stable release ( 1.1 ) :

https://mageia.org/pipermail/mageia-i18n/2011-June/002070.html

The steps required are :

- Create a package of django-haystack 1.2
- Create a package of pysolr
- Create a package of tx 1.1 

for cauldron

- Backport them on a test vm
- Install tx 1.1 
  - play a little bit with it ( see if there is no obvious crasher )
  - see if the configuration must be changed ( that's likely )

- Warn i18n people that we will do the update, 1 week before
- do the upgrade 
  - backup of the db
  - install needed rpms
  - run the command to migrate schema
- ask for feedback
- fix what would break :)
- announce it on the blog

We should make sure we can rollback to a previous version
