How to upgrade OMS
New and past versions of OMS software are made available to you directly from VIAVI. Use the OMS upgrade tool to check for, download, or install a version of OMS.
Internet access to (port 80) is required on the system interacting with the VIAVI upgrade repository. This includes checking for upgrades and downloading upgrades. Only OMS requires this; none of your managed assets do.
Only if your application or appliance is managed by OMS, LAN access to the OMS system over port 8008 (default) is required for downloading upgrades. The port can be changed in OMS.
Proxy settings can be used if direct Internet access is unavailable.
The OMS upgrade tool allows you to:
Check the VIAVI upgrade repository for old and new versions of OMS.
Download any available version of OMS for offline installation.
Install any available version of OMS without needing to leave the OMS interface.
How to retrieve a list of available OMS versions
A listing of OMS software versions to upgrade or downgrade to is available directly in OMS. Connect to the VIAVI upgrade repository to retrieve the latest listing of available versions.
Note: Interacting with the upgrade repository requires web connectivity over TCP port 80 or 8008 (by default) on the OMS system. This can be achieved with direct connectivity from OMS to the web or by configuring a proxy in the proxy configuration settings of OMS for downloads. The upgrade repository is hosted by VIAVI and no public mirrors are used.
To ensure your product is using the latest code available, always check the in-product update capability even if you have recently installed. It is strongly recommended that all product updates and upgrade are performed using the in-product update methods instead of installing the executable using Windows File Explorer.

Upgrade settings
There are several settings that change the behavior of version upgrades.
Check for upgrades
If selected, OMS periodically checks for upgrades. Scheduled transfers and installs rely on knowing if new versions exist.
If cleared, users must manually check for available upgrades before any scheduled transfers or installs can occur.
Show downgrade options
If selected, any available downgrade versions are displayed in the available versions list.
It is recommended to leave this cleared (disabled) if downgrading to previous versions is not desirable.
Preferred speed (Kbps)
Sets the preferred maximum transfer speed in kilobits per second.
Use the value '0' to disable this bandwidth restriction.
Use proxy server
If selected, a proxy server is used for downloading upgrade versions.
Proxy type
Sets which type of proxy server to connect to.
Proxy address
The IP address or DNS name of the proxy server.
Proxy port
The port number accepting connections to the proxy server.
Proxy user
