Kolab - choosing your platform

Kolab Systems maintains the build infrastructure so that the Kolab Community can build packages on many platforms. Not all releases of Kolab are available for all platforms. And Kolab subscriptions with professional support are not equally available for all releases on all platforms.

TIP: If you are new to Kolab, you might want to first read about our Release Model and the software subscription based Support Model.

Understanding Primary, Secondary and Tertiary Platforms

A Primary Platform is a preferred platform for supported releases of Kolab. All releases for these platforms are maintained for the full time of extended support and security updates until the platform itself is declared End Of Life (EOL) by its provider.

A Secondary Platform is a platform that is under active, ongoing support for Kolab. Releases for these platforms arrive one quarter after releases for the Primary Platforms. All releases for these platforms are maintained for the full time of extended support and security updates until there is a new major release of this platform by its provider.

When the platform provider releases a new major version, you will need to update to their most recent version within a grace period of half a year. If your current version of Kolab is not available for the new major release, you will also need to update your version of Kolab in order to remain within support.

A Tertiary Platform is a platform for which support is available only through third party agreement or explicit contract. Where sufficient customer commitment exists, Tertiary Platforms may be promoted to Secondary Platforms.
