h1. How to Update from v22-redux (Linux)

2.2-redux version is installed on CentOS6 and uses redux.  Its upgrade to Leginon/Appion 3.0 release does not require os upgrade.

h1. Upgrade processing server

h2. Download myami 3.0 source code

<pre>

svn co http://emg.nysbc.org/svn/myami/branches/myami-3.0/

</pre>

h2. Install Appion/Leginon Packages

h3. Install all the myami python packages _except appion_ using the following script:

<pre>

cd /your_download_area

cd myami

sudo ./pysetup.sh install

</pre>

That will install each package, and report any failures.  To determine the cause of failure, see the generated log file "pysetup.log".  If necessary, you can enter a specific package directory and run the python setup command manually.  For example, if sinedon failed to install, you can try again like this: 

<pre>

cd sinedon

sudo python setup.py install

</pre>

h3. Move leginon.cfg/instruments.cfg/sinedon.cfg if it was saved with the old installation.

Run this script to find out where it was:

<pre> 

cd /your_download_area/myami/leginion/

./configcheck.py

</pre>

If the script can not find leginon.cfg, and you found a copy of leginon.cfg in $PYTHONSITEPKG/leginon/config from the last installation, move that leginon.cfg to $PYTHONSITEPKG/leginon.

h1. Upgrade web server

Rename your current myamiweb at the document root of the web server to something else as a backup.

h2. install the 3.0 version of redux and pyami.

h3. Follow [[Install_Redux_image_server]] instruction but note the following

* The old version in python's site-packages directory will be overwritten.

* The old redux.cfg, if in the installation, is still applicable.

* Make sure you run fftwsetup.py if you have odd-dimension camera such as Gatan K2. 

h2. Install updated Web viewers and tools

See [[Install the Web Interface]] section in Complete Installation Chapter to put the new myamiweb tools to document root for the web server.  There is no need to run WebToolSetupWizard, however.  See below.

h2. Copy config.php from your older myamiweb backup to the new myamiweb.

h2. Import new versions of Leginon Applications

All MSI Leginon applications need to be upgraded or it will not run.  Use the Web administrator tool to do this as shown in [[Steps_involved_in_the_installation#2.-Import-Applications]]
