Is your CMS reaching end of life?
The major traditional content platforms all publish an end-of-support date, after which security fixes stop. Reaching it does not break your site the day it passes, but it turns a planned migration into an urgent one. Below is where the main platforms stand, taken from each vendor's own lifecycle page, with the migration guide for each next to it.
When support ends for the major platforms.

WordPress, Webflow, Contentful, and Sitefinity don't share a single deadline.
Not every CMS sunsets a version on a calendar. WordPress backports security fixes across versions and has no hard end-of-life, so the reason to leave it is outgrowing it rather than a deadline. Hosted platforms like Webflow and Contentful run one continuously-updated service, so there is no version to reach end of life, though the questions of ownership and portability still apply. Progress Sitefinity runs a rolling lifecycle with long-term-support branches rather than one shared date; check your exact version against the Sitefinity lifecycle policy. For any of these, the decision is about fit, which we covered in five signs you've outgrown your CMS.
LightCMS sent its shutdown date to customers by email, then the site itself went dark.
LightCMS is the platform still searched for by name. Its own site carried the announcement by June 2020: “we will no longer be offering the LightCMS Service and have announced its end of life” (archived notice). The shutdown date itself went to customers by email — a Last Date of Service of 31 May 2020, later revised to 31 October 2020 (preserved in third-party records). The site has since gone dark, so the announcement survives only in the Internet Archive. It has no row in the table above because every date there links a vendor page you can still check, and no such page exists for LightCMS: the emailed date survives only second-hand.
A retired hosted platform takes the admin, the export tooling and the content with it, so there is no version to upgrade to and no support tier to buy. Recovering a site in that state means rebuilding from whatever exists outside the platform: a crawl or archive of the public pages, local copies of assets, and whatever the team still holds. That is a different exercise from a migration off a running system, and it is worth reading vendor lock-in for how much of the exit cost gets fixed long before the shutdown notice arrives. Where content is still reachable, the pre-migration checklist covers what to capture first.
Every date is taken from the vendor's own lifecycle page.
