We have not removed existing support, but new CloudVision releases won't be tested with these older EOS trains.
While most CloudVision features will likely continue to function, any support for these older trains will be on a best-effort basis. We strongly recommend upgrading your EOS devices via CloudVision to a supported release. Posted on
