View source for Howto16r1:Firmware Upgrade V15r1 V16r1

== Applies To ==
This information applies to:

* All 16r1 capable innovaphone devices
: For a general overview of the upgrade process and a list of supported devices with 16r1, see [[Howto:Firmware Upgrade]]
== Licenses ==
In case of cloud or rental model, don't worry about licenses.

If the system is licensed on premise, you'll need to regenerate the license file for v16 in https://portal.innovaphone.com/ and load into the system before upgrade (The system needs to have the SSC up to date).

== Migration Policy ==
Here is how you upgrade a system from 15r1 to 16r1.

<span style="color:red; font-weight: bold">Before you begin, be sure that your whole installation is running the latest 15r1 service release.</span><br>

=== AP Upgrade to Image 130xxx ===
* Please Upgrade as first your Application Platform to Image Version 130xxx. After that you can go ahead.

=== TechAssist Upgrade Helper ===
* Before you start, make sure that all TechAssist tests (you will receive the required tests in the last update in the previous major version) labelled <code>Pre Upgrade: xy</code> are positive, if available
* When you are finished, make sure that all TechAssist tests (you will receive new tests with the upgrade) are positive

== Changes visible to the end customers ==
Listed here are changes that should be communicated by resellers to end users prior to a upgrade, as the change will be visible/audible in the behaviour of the application/device.

== Manual steps needed after upgrade ==
If the installer is not used for a new installation, some new default settings are not set. Please evaluate per app whether you want to configure the new default settings manually.

== New Apps ==
New Apps will not be installed automatically by the upgrade. The installation description of new apps is usually in the concept article. Please rate per app whether you want to install/use the new app and configure it manually.

==Known Problems==
===Long Update-duration===
When you update, it can be up to 10 minutes before you have access to your app platform again.

===App Platform doesn't boot after Upgrade===
If you didn't upgrade the AP Image before upgrading the apps like describe [[#AP_Upgrade_to_Image_130006|here]] and the AP isn't reachable via http(s), but still via ssh, please follow these [[Reference14r2:Concept_App_Platform#It_still_doesn't_start|instructions]] to get the AP work correct again.

== Resources Considerations ==
New firmware always has more features which in turn requires more resources. Growing firmware will thus consume both more flash and RAM for sure. A given system configuration will run flawlessly after a firmware largely only if there is still enough memory left after boot.

Standard configurations which are according the specs will run on all supported hardware. However, unusual configurations may not. It is a good idea to examine both flash and RAM memory left on high load situations in your existing configuration to see if there is enough resources left for an upgrade. Please find details in Reference:Device Health Check.

=== RAM ===
As a rough rule of thumb, a 15r1 release will consume the same amount of RAM compared to a v14r2 firmware.

=== Flash Memory  ===
