However, some bullets:
* DEISA uses the official UNICORE @ SourceForge release as released
according to roadmaps from the UNICORE Forum and guidance of the UNICORE
Forum technical board

* Deployments are typically tested on a per site basis, before a greater
production deployment is undertaken in whole DEISA, e.g. using a few nodes
on a supercomputer especially for testing the new release before it goes in
full production for the whole supercomputer.

* Agreements on specific dates ensure that whole DEISA is operating on the
same UNICORE version afterwards. 

* There is no automation basically in the process, therefore administrators
ensure that the deployments work after making their own tests. However,
since UNICORE 5 is stable over many years this process is typically not very
cumbersome.

* DEISA is evaluating UNICORE 6 for production, but there are no news yet.
