Upgrading the Software Release
To upgrade the software:
1. Read carefully chapter 6 "Interoperability & Limitations" of the Release
Note of the new version you want to install.
2. Go to the Setup tab and choose the Download category.
3. Refer to section ’Setup/Download’ on page 180.
When you apply a new software version, a smooth upgrade mechanism
applies, for each job:
1. The job is created in the new version, in mute mode.
2. Once the job is properly running, it is unmuted and the job in the old
version is muted.
3. The job in the old version is deleted.
The smooth upgrade mechanism is not available for jobs that use a
virtual IP address, for instance TS over IP unicast inputs or Web TV
outputs when the stream is available on the local Web server. Those
jobs are stopped and recreated in the version.
Note that TS over IP outputs do not use a virtual IP address, and thus
the smooth upgrade can be used.
The smooth upgrade can be used only if the system CPU and
memory resources are sufficient to duplicate the jobs. Otherwise,
jobs are stopped and recreated in the new version.
