Support Lifecycle of MontaVista's Products
MontaVista provides lifecycle-based support for its products, from General Availability through long-term maintenance. Customers can also extend maintenance beyond the standard lifecycle with Extended Long Term Maintenance (ELTM).
Product Support Lifecycle
Product Support Schedule
- All MontaVista product subscribers can sign up to annually renew their agreement with different levels of support, ranging from Standard to Dedicated Engineering Services (DES) support to cover all support activities, as well as access to the MontaVista Zone content delivery portal.
- Customers also have the option to extend the maintenance of a product by purchasing Premium Long Term Maintenance (PLTM) and Long Term Maintenance (LTM). The Premium Long Term Maintenance phase of a product life cycle typically last for 3 years followed by two years of LTM before End of Life (EOL) in the CGX line of products.
- For MVShield, the lifecycle stages follow the underlying community Linux lifecycle, where we have prioritised support cycles for active community products, and the latest minor release of each major release supported.
- Once the LTM phase has ended customers still have option to extend the maintenance of a product, delaying the EOL date, using our Extended Long Term Maintenance (ELTM) and Sustaining Support services.
| Edition | Status | Effective Date | GA | PLTM | LTM | ELTM/EOL |

MontaVista Linux
For CGX, a new product begins with General Availability (GA) for five years. This is typically followed by three years of Premium Long Term Maintenance (PLTM) and two years of Long Term Maintenance (LTM) before the product reaches End of Life (EOL).
Community-Aligned Support
For MVShield, the GA, PLTM and LTM stages follow the lifecycle of the underlying community Linux distribution. MontaVista prioritizes support for active community products and the latest minor release of each supported major release.
General Availability (GA)
Baselines built on the most recent community-supported minor version.
Premium Long Term Maintenance (PLTM)
The base community version is no longer maintained by the community but still aligns with a communitysupported major version. PLTM also covers the newest minor version of a major release that most recently ended community support.
Long Term Maintenance (LTM)
The newest minor version of a major release that is two releases behind the current community major release. LTM also covers non-latest minor versions of major releases one level behind the current major release.
Service Levels by Lifecycle Stage
The standard level of service changes as a product progresses through its lifecycle. During GA, MontaVista proactively addresses Medium, Serious and Critical CVE defects, while later maintenance stages focus progressively on higher-severity issues.
| Stage | Proactive Service | Reactive Service |
|---|---|---|
| GA | Medium Serious Critical | All |
| PLTM | Serious Critical | Serious Critical Escalated |
| LTM | Critical | Critical Escalated |
| ELTM | -- | Critical |
Extending Product Maintenance
For all products, customers can extend maintenance after the LTM phase and delay the product's EOL date with Extended Long Term Maintenance (ELTM).
