WMS versions lifecycle

Introduction

This document describes all major stages of a WMS version lifecycle (e.g. End of Development, End of Life, End of Support) and their differences. In short, a major WMS version passes the following stages: 

1. Global Availability 
2. End of Development (end of sales)
3. End of Life
4. End of Support

When globally available, a WMS version is being further developed, with new features released, bug fixes, as well as performance and security improvements. The other two stages (End of Development and End of Life) are described in detail below. 

End of Development (EOD)

WMS version is considered End of Development (end of sales) when the next major version becomes globally available. While the WMS version is at the End of Development stage and until it is End of Life: 

• Critical bug fixes and security improvements are delivered.
• No new features are delivered.  
• Wildix continues to provide technical support.
• Newly created systems on WMP are delivered with the next major WMS version
  

• For subscription-based PBXs, an upgrade to the next major version is arranged automatically:

1. 1. Partners are encouraged to do the upgrade by themselves
   2. Wildix team schedules an update and notifies Partners about the upcoming date (2 months in advance). On the announced date the upgrade is performed automatically if the Partner doesn’t do the upgrade by themselves.

• For LifeTime PBXs, there is a Promo to convert LifeTime to aaS, with the possibility to roll back to a version that is still supported. No automatic upgrade is possible. 

End of Life (EOL)

LifeTime PBXs that were not converted to aaS during the End of Development stage, remain with a WMS version that is End of Life.

 When WMS version is End of Life:

• There are no security updates or patches.
• There is no guarantee of Microservices and other services backward compatibility due to third party software updates (e.g. browsers).
• X times support cost
• The service is provided for as long as the Support fee is being paid and as long as it is technically possible.
