Mattermost EOSL: Frequently Asked Questions
What does end of service life (EOSL) mean for Mattermost equipment?
EOSL is the date after which Mattermost no longer sells support contracts or ships updates for a product. The equipment keeps working; only the OEM's willingness to support it ends. Third-party maintenance takes over from that date with engineering support and replacement parts.
Can I get support for Mattermost products that are already past EOSL?
Yes. 54 Mattermost products in this list are already past their EOSL date and all remain supportable. We hold spares for every model we quote and cover equipment for 5+ years past the OEM date.
How far ahead should I plan for a Mattermost EOSL date?
Start 6 to 12 months before the EOSL date. That is enough time to compare the OEM's final renewal against third-party maintenance, decide whether to extend or refresh, and move coverage without a gap. We return an indicative price within 24 hours and a firm quote within 48.
